100 Watt AC-DC Converters with PFC S Series

Universal input voltage range
Power factor >0.95, harmonics <IEC/EN 61000-3-2
Input over- and undervoltage lock-out
Efﬁcient input ﬁlter and built-in surge and transient suppression circuitry
Fully isolated outputs
Outputs overload, open- and short-circuit proof
No derating over entire operating temperature range Safety according to IEC/EN 60950 Table of Contents Page Summary The S 4000/S 5000 series of AC-DC converters represents a ﬂexible range of power supplies for use in advanced elec- tronic systems. Features include full power factor correc- tion, high efﬁciency, high reliability, low output voltage noise and excellent dynamic response to load/line changes. The converter inputs are protected against surges and tran- sients occurring at the source lines. An input over- and undervoltage lock-out circuitry disables the outputs if the input voltage is outside the speciﬁed range. Inrush current limitation is included preventing circuit breakers and fuses from being damaged at switch-on. All outputs are overload, open- and short-circuit proof and are protected against overvoltages by means of a built-in suppressor diode. The outputs can be inhibited by a logic signal applied to the connector pin 18 (i). If the inhibit func- tion is not used pin 18 must be connected to pin 14 to en- able the outputs. LED indicators display the status of the converter and allow visual monitoring of the system at any time. Full input to output, input to case, output to case and output to output isolation is provided. The modules are designed and built according to the international safety standards IEC/EN 60950 and have been approved by the safety agencies LGA (Germany) and UL (USA). The UL Mark for Canada has been ofﬁcially recognized by regulatory au- thorities in provinces across Canada. The case design allows operation at nominal load up to 71°C in a free air ambient temperature. If forced cooling is provided, the ambient temperature may exceed 71 °C but the case temperature must remain below 95 °C under all conditions. A temperature sensor generates an inhibit signal which disables the outputs if the case temperature TC exceeds the limit. The outputs are automatically re-enabled when the temperature drops below the limit. Various options are available to adapt the converters to in- dividual applications. The modules may either be plugged into 19" rack systems according to DIN 41494, or be chassis mounted. Important: These products are intended to replace the LS 1000 and LS 2000 in order to comply with IEC/EN 61000-3-2.

Cassette Style 100 Watt AC-DC Converters S Series PFC Edition 01/01.2001 3/27 Functional Description The input voltage is fed via an input fuse, an input ﬁlter, a rectiﬁer and an inrush current limiter to a single transistor boost converter. This converter provides a sinusoidal input current (IEC/EN 61000-3-2, class D equipment) and sour- ces a capacitor with a voltage of 360-370 V DC. This ca- pacitor sources a single transistor forward converter. Each output is powered by a separate secondary winding of the main transformer. The resultant voltages are rectiﬁed and their ripples smoothed by a power choke and an output ﬁlter. The control logic senses the main output voltage Uo1 and generates, with respect to the maximum admissible output currents, the control signal for the primary switching transistor. The second output of double output units is controlled by the main output, but has independent current limiting. If the main output is driven into current limitation, the second out- put voltage will fall as well and vice versa.

When checking this function the absolute maximum input voltage rating Ui abs should be considered! Between Ui min and the undervoltage lock-out level the output voltage may be below the value defined in table: Output data (see: Technical Information: Measuring and Testing). Input Transient Protection A VDR together with the input fuse and a symmetrical input ﬁlter form an effective protection against high input tran- sient voltages. Input Fuse A fuse mounted inside the converter protects the module against severe defects. (If operated from a DC-source this fuse may not fully protect the module when the input volt- age exceeds 200 V DC! In applications where the convert- ers operate at source voltages above 200 V DC an external fuse or a circuit breaker at system level should be installed!)

Reverse Polarity Protection Should the input voltage to the unit be supplied from a DC source the built-in bridge rectiﬁer provides reverse polarity protection. (For DC-input operation, please consult your lo- cal Power-One partner.) Inrush Current Limitation The modules of the versions -7, incorporate an NTC resis- tor in the input circuitry which – at initial turn on – reduces the peak inrush current value by a factor of 5...10 to protect connectors and switching devices from damage. Subse- quent switch-on cycles within short periods will cause an increase of the peak inrush current value due to the warm- ing-up of the NTC resistor. See also: E option. Inrush Current Peak Value The inrush current peak value (initial switch-on cycle) can be determined by following calculation:

Cassette Style 100 Watt AC-DC Converters S Series PFC Edition 01/01.2001 9/27 Output Voltage Regulation of Double Output Modules Output 1 is under normal conditions regulated to Uo1 nom, independent of the output currents. Uo2 is dependent upon the load distribution. If both outputs are loaded with more than 10% of Io nom, the deviation of Uo2 remains within ±5% of the value of Uo1. The following 3 ﬁgures show the regulation with varying load distribution. If Io1 = Io2 or the two outputs are connected in series, the de- viation of Uo2 remains within ±1% of the value of Uo1 pro- vided that a total load of more than 10% of Io nom is applied. Two outputs of a single S 5000 module connected in paral- lel will behave like the output of a S 4000 module; the paral- leled output is fully regulated. No precautions are neces- sary in using the R-input and the test sockets. Uo Uo nom 0.98 0.5 0.5 1.0 Io1 IoL Io Io nom 05001 Fig. 9 Uo1 vs. Io1 (typ.) of single output units Thermal Considerations If a converter is located in free, quasi-stationary air (con- vection cooling) at the indicated maximum ambient tem- perature TA max (see table: Temperature specifications) and is operated at its nominal input voltage and output power, the temperature measured at the Measuring point of case temperature TC (see: Mechanical Data) will approach the indicated value TC max after the warm-up phase. However, the relationship between TA and TC depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow and temperature of surrounding compo- nents and surfaces. TA max is therefore, contrary to TC max, an indicative value only. Caution: The installer must ensure that under all operat- ing conditions TC remains within the limits stated in the table: Temperature specifications. Notes: Sufficient forced cooling or an additional heat sink allows TA to be higher than 71°C (e.g. 85°C) if TC max is not exceeded. For -7 or -9 units at an ambient temperature TA of 85°C with only convection cooling, the maximum permissible current for each output is approx. 40% of its nominal value as per figure. 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 50 60 70 80 90 100 I o/Io nom TA [°C] 0.9 1.0 Forced cooling 05089 TA min TC max Convection cooling Fig. 8 Output current derating versus temperature for -7 and -9 units. Thermal Protection A temperature sensor generates an internal inhibit signal which disables the outputs if the case temperature exceeds TC max. The outputs are automatically re-enabled if the tem- perature drops below this limit. It is recommended that continuous operation under simul- taneous extreme worst case conditions of the following three parameters be avoided: Minimum input voltage, maximum output power and maximum temperature. Output Protection Each output is protected against overvoltage which could occur due to a failure of the control circuit by means of a voltage suppressor diode which, under worst case condi- tions, may become a short circuit. The suppressor diodes are not designed to withstand externally applied over- voltages. Overload at any of the two outputs will cause a shut-down of both outputs. A red LED indicates the over- load condition. Parallel or Series Connection of Units Single or double output units with equal nominal output volt- age can be connected in parallel without any precautions using option T. With option T (current sharing), all units share the current approximately equally. Single output units and/or main and second outputs of dou- ble output units can be connected in series with any other (similar) output. Note: – Parallel connection of double output units should always include both, main and second output to maintain good regulation of both outputs. – Not more than 5 units should be connected in parallel. – Series connection of second outputs without involving their main outputs should be avoided as regulation may be poor. – The maximum output current is limited by the output with the lowest current limitation if several outputs are con- nected in series.

If the sense lines are connected at the load rather than directly at the connector, the user should ensure that Uo max (between Vo1+ and Vo1–) is not exceeded. We recommend connecting the sense lines directly at the fe- male connector. For further information, please refer to: Application Notes . To ensure correct operation, both sense lines (S+ and S–) should be connected to their respective power outputs (Vo1+ and Vo1–) and the voltage difference between any sense line and its respective power output pin (as meas- ured on the connector) should not exceed the following val- ues: Table 6: Maximum Voltage compensation allowed using sense lines Output Total voltage difference Voltage difference voltage between sense lines and between their respective outputs Vo – and S– 5.1 V <0.5 V <0.25 V 12 V, 15 V <1.0 V <0.25 V If the output voltages are increased above Uo nom via R-in- put control, option P setting, remote sensing or option T, the output currents must be reduced accordingly so that Po nom is not exceeded. Important: The output terminals Vo1+ and Vo1 – must always be connected to the load before connecting the sense lines S+ and S –, otherwise the unit will be dam- aged.

Warning: – Uext shall never exceed 2.75 V DC. – The value of R'ext shall never be less than the lowest value as indicated in table R'ext (for U0 >U0 nom) to avoid damage to the unit! Remarks: – The R-Function excludes option P (output voltage ad- justment by potentiometer). – If the output voltages are increased above Uo nom via R- input control, option P setting, remote sensing or option T, the output current(s) should be reduced accordingly so that Po nom is not exceeded. – The R-input (as well as option P) is related to the main output. – With double output units the second output follows the value of the controlled main output. Resistor values as indicated for the single output units should be used. – For correct output voltage adjustment of double output units the external wiring of the outputs should be accord- ing to ﬁg.: R-Function for different output configuration depending upon the desired output conﬁguration. – In case of parallel connection the output voltages should be individually set within a tolerance of 1...2%.

The positive test socket is protected by a series resistor (see: Functional Description, block diagrams). The voltage measured at the test sockets is approximately 30 mV lower than the value measured at the output terminals. In case of double output units externally connected in se- ries for Uo = 24 V, 30 V or 48 V the monitored output volt- age is 12 V, 15 V or 24 V respectively. Battery Charging/Temperature Sensor The LS are intended for lead acid battery charger applica- tions. For an optimum battery charging and life expectancy of the battery an external temperature sensor may be con- nected to the R-input. The sensor is mounted as close as possible to the battery pole and adjusts the output voltage of the LS unit according to the temperature of the battery (which is related to the load of the battery and the ambient temperature). Depending on the cell voltage and the temperature coeffi- cient of the battery, different sensor types are available. For more information please ask Power-One.

The S series AC-DC converters are components, intended exclusively for inclusion within other equipment by an in- dustrial assembly operation or by professional installers. In- stallation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation require- ments of the end-use application. Connection to the system shall be made via the female con- nector H15 (see: Accessories). Other installation methods may not meet the safety requirements. The AC-DC converters are provided with pin no. 24 ( ), which is reliably connected with their case. For safety rea- sons it is essential to connect this pin with the protective earth of the supply system. An input fuse is built-in in the connection from pins no. 30 and 32 (P∼) of the unit. Since this fuse is designed to pro- tect the unit in case of an overcurrent and does not neces- sarily cover all customer needs, an external fuse suitable for the application and in compliance with the local require- ments might be necessary in the wiring to one or both input potentials, pins nos. 26 and 28 and/or nos. 30 and 32. Important: Whenever the inhibit function is not in use, pin no. 18 (i) should be connected to pin no. 14 (S–/Vo1–) to enable the output(s). Do not open the modules, or guarantee will be invali- dated. Due to high current values, all LS units provide two inter- nally parallel connected contacts for certain paths (pins 4/6, 8/10, 26/28 and 30/32, respectively). It is recommended to connect load and supply to both female connector pins of each path in order to keep the voltage drop across the con- nector pins to an absolute minimum and to not overstress the connector contacts if currents are higher than approx. 8 A. The connector contacts are rated 8 A over the whole temperature range. Make sure that there is sufficient air flow available for con- vection cooling. This should be verified by measuring the case temperature when the unit is installed and operated in the end-use application. The maximum specified case tem- perature TC max shall not be exceeded. See also: Thermal Considerations. Check for hazardous voltages before altering any connec- tions. Ensure that a unit failure (e.g. by an internal short-circuit) does not result in a hazardous condition. See also: Safety of operator accessible output circuit. Cleaning Agents In order to avoid possible damage, any penetration of cleaning fluids is to be prevented, since the power supplies are not hermetically sealed.

The use in a pollution degree 2 environment
The UL 1950 recognition limits the minimum input voltage to Ui = Ui min + 5 V AC = 90 V AC if the case temperature exceeds 90°C. The AC-DC converters are subject to manufacturing sur- veillance in accordance with the above mentioned UL, CSA, EN and with ISO 9001 standards. Isolation The electric strength test is performed as factory test in ac- cordance with IEC/EN 60950 and UL 1950 and should not be repeated in the field. Power-One will not honour any guarantee claims resulting from electric strength field tests. Important: Testing by applying AC voltages will result in high and dangerous leakage currents flowing through the Y-capacitors (see fig.: Block diagram).

This feature enables compensation for voltage drops across the connector and wiring. Option P is not recommended if units are connected in parallel. Option P excludes the R-function. With double output units both outputs are affected by the potentiometer setting (dou- bling the voltage setting if the outputs are in series). If the output voltages are increased above Uo nom via R-in- put control, option P setting, remote sensing or option T, the output current(s) should be reduced accordingly so that Po nom is not exceeded. -9 Extended Temperature Range Option –9 extends the operational ambient temperature supplies provide full nominal output power with convection cooling.

To use this facility, simply inter- connect the T pins of all modules and make sure, that pin 14, the S – pin (S 4000) or the Vo1 – pins (S 5000) are also connected together. The load leads should have equal length and cross section to ensure equal voltage drops. Not more than 5 units should be connected in parallel. If output voltage adjustment is requested we strongly recommend to use the R-input instead of option P , as with option P the re- quired setting accuracy is dif ﬁcult to achieve. The output voltages must be individually set prior to paralleling to within a tolerance of 1...2% or the R pins should be con- nected together.

A logic "low" (JFET output) or "high" signal (NPN output) is generated at pin 20 as soon as one of the moni- tored voltages drops below the preselected threshold level Ut. The return for this signal is Vo1–. The D output recovers when the monitored voltage(s) exceed(s) Ut + U h.

Cassette Style 100 Watt AC-DC Converters S Series PFC Edition 01/01.2001 25/27 V ACFAIL Signal (VME) Available for units with Uo1 = 5.1V This option de ﬁnes an undervoltage monitoring circuit for the input or input and main output voltage equivalent to op- tion D and generates the ACFAIL signal (V signal) which conforms to the VME standard. The low state level of the ACFAIL signal is speci ﬁed at a sink current of IV ≤ 48 mA to UV ≤ 0.6 V (open-collector out- put of a NPN transistor). The pull-up resistor feeding the open-collector output should be placed on the VME back plane. After the ACFAIL signal has gone low, the VME standard requires a hold-up time th of at least 4 ms before the 5.1 V output drops to 4.875 V when the output is fully loaded. This hold-up time th is provided by the internal input capaci- tance. See also ﬁg.: Hold-up Time versus Output Power.
