PRODUCT SPECIFICATION 3 (4) Prepared (also subject responsible if other) No. SEC/S Kevin Zhou 1/1301-BMR 638/2 Uen Approved Checked Date Rev Reference 2011-02-24 E Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL 60950-1 Safety of Information Technology Equipment. IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards:

  • Electrical shock
  • Energy hazards
  • Fire
  • Mechanical and heat hazards
  • Radiation hazards
  • Chemical hazards On-board DC/DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any safety requirements without “Conditions of Acceptability”. Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. Component power supplies for general use should comply with the requirements in IEC 60950-1, EN 60950-1 and UL 60950-1 Safety of Information Technology Equipment. There are other more product related standards, e.g. IEEE 802.3 CSMA/CD (Ethernet) Access Method, and ETS-300132-2 Power supply interface at the input to telecommunications equipment, operated by direct current (dc), but all of these standards are based on IEC/EN/UL 60950-1 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL 60950-1 recognized and certified in accordance with EN 60950-1. The flammability rating for all construction parts of the products meet requirements for V-0 class material according to IEC 60695-11-10, Fire hazard testing, test flames — 50 W horizontal and vertical flame test methods. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in accordance with IEC/EN/UL 60950-1. Isolated DC/DC converters It is recommended that a slow blow fuse is to be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions:
  • Isolate the fault from the input power source so as not to affect the operation of other parts of the system.
  • Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (V iso) between input and output is 1500 Vdc or 2250 Vdc (refer to product specification).

24 V DC systems

The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. 48 and 60 V DC systems If the input voltage to the DC/DC converter is 75 Vdc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 Vdc. If the input power source circuit is a DC power system, the source may be treated as a TNV-2 circuit and testing has demonstrated compliance with SELV limits in accordance with IEC/EN/UL60950-1. Non-isolated DC/DC regulators The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions.

It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and the equipment ground or chassis. A ground layer will increase the stray capacitance in the PCB and improve the high frequency EMC performance. Output ripple and noise Output ripple and noise measured according to figure below.

PRODUCT SPECIFICATION 2 (6) Prepared (also subject responsible if other) No. EJANLLI 3/1301-BMR 638/2 Uen Approved Checked Date Rev Reference SEC/D (Julia You) ECHWANG 2008-10-24 E Operating information Input Voltage The input voltage range is 18 to 36Vdc. At input voltages exceeding 36 V, the power loss will be higher than at normal input voltage and T ref must be limited to absolute max +110°C. The absolute maximum continuous input voltage is 40 Vdc. Turn-off Input Voltage The DC/DC converters monitor the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 1V. Remote Control (RC) The modules are equipped with a remote On/Off control function. An optocoupler in the remote control circuit provides a galvanic isolation (1500V DC minimum) between the remote control pins and the rest of the module’s circuity. Positive and negative RC logic options are available. Cycling (Off and On sequence) of the RC input will restart the module if latched after activation of the output overvoltage protection function. The standard version has a “positive logic” remote control and the module will be off until a sufficient current between the RC pins is provided. The figure above presents an example of a circuit which turns on the standard version module. The minimum current to guarantee the activation of the RC input is 1,5mA. The minimum activation voltage over the RC pins is 5.0V. To guarantee that the RC input is not activated, the current must be lower than 50μA or the voltage lower than 1,3V. Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the DC/DC converter. It is important that the input source has low characteristic impedance. The converters are designed to be stable without external capacitors on input or output. However, the module performance can be enhanced by adding external capacitors as described under External Decoupling Capacitors. If the input volta ge source contains significant inductance, the addition of a 470 μF/40 V capacitor across the input of the converter will ensure stable operation. The capacitor is not required when powering the DC/DC converter from an input source with an inductance below10 μH. External Decoupling Capacitors When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved by addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. Ceramic capacitors will also reduce any high frequency noise at the load. It is equally important to use low resistance and low inductance PCB layouts and cabling. External decoupling capacitors will become part of the control loop of the DC/DC converter and may affect the stability margins. As a “rule of thumb”, 100 μF/A of output current can be added without any additional analysis. The ESR of the capacitors is a very important parameter. Power Modules guarantee stable operation with a verified ESR value of >10 mΩ across the output connections. For further information please contact your local Ericsson Power Modules representative. Output Voltage Adjust (Vadj) The product has an Output Voltage Adjust pin (Vadj). This pin can be used to adjust the output voltage above or below Output voltage initial setting. When increasing the output voltage, the voltage at the output pins (including any remote sense compensation ) must be kept below the threshold of the over volta ge protection, (OVP) to prevent the converter from shutting down. At increased output voltages the maximum power rating of the converter remains the same, and the max output current must be decreased correspondingly. To increase the voltage the resistor should be connected between the V adj pin and +Sense pin. The resistor value of the Output voltage adjust function is according to information given under the Output section for the respective product. To decrease the output voltage, the resistor should be connected between the Vadj pin and —Sense pin.

PRODUCT SPECIFICATION 3 (6) Prepared (also subject responsible if other) No. EJANLLI 3/1301-BMR 638/2 Uen Approved Checked Date Rev Reference SEC/D (Julia You) ECHWANG 2008-10-24 E Operating information continued Parallel Operation Two or more products may be paralleled for redundancy or increased output power. External active load sharing circuit are recommended to provide the maximum balanced current sharing. Remote Sense The product has remote sense that can be used to compensate for voltage drops between the output and the point of load. The sense traces should be located close to the PCB ground layer to reduce noise susceptibility. The remote sense circuitry will compensate for up to 10% voltage drop between output pins and the point of load. If the remote sense is not needed +Sense should be connected to +Out and -Sense should be connected to -Out. Over Temperature Protection (OTP) The product is protected from thermal overload b y an internal Over Temperature Protection circuit (OTP). When the PCB temperature (TC reference point) exceeds the OTP T threshold value, the output voltage will be gradually decreased. This will decrease the power loss inside the DC/DC power module and protect the module from hazardous temperatures. Over Voltage Protection (OVP) The module includes an output Over Voltage Protection (OVP) function. In the unlikely event of an output over voltage condition, the OVP circuit will shut down the output voltage. The module will be latched in “Off” state unless either the input voltage or RC input is cycled (switched Off and On again). Over Current Protection (OCP) The moduleinclude current limiting circuitry for protection at continuous overload. In case of overload, the output voltage will significantly decrease. The converter will resume normal operation after removal of the overload. The load distribution should be designed for the maximum specified output short circuit current. Pre-bias Start-up The module is able to start-up properly under pre-bias output condition. During the start-up, the module does not sink current from an external pre-bias source present at the output terminals. Power Good “Power Good” function is provided. It is a “negative logic” open collector output which can drive to “low” an external circuit when the module operates normally. The PG output will turn level “high” during fault conditions (e.g. over temperature or over voltage) or when the output is turned off with the remote control. Auxiliary output voltage (AUX) The module provides a power source referred to – sense terminal. It is intended to be used as a power source for external circuits, e.g. remote control. The auxiliary output voltage is active whenever an input voltage in range between from 17V to 40V is provided. The nominal auxiliary output voltage is 10V. Maximum allowed load is 50mA.The auxiliary output source is not short circuit protected. If it is overloaded, the main converter will be switched off. An example of a 5V/45mA power supply driven by the auxiliary output voltage is given in the figure below.

PRODUCT SPECIFICATION 4 (6) Prepared (also subject responsible if other) No. EJANLLI 3/1301-BMR 638/2 Uen Approved Checked Date Rev Reference SEC/D (Julia You) ECHWANG 2008-10-24 E Thermal Consideration General The PKY converters are designed to operate in different thermal environments and sufficient cooling must be provided to ensure reliable operation. Cooling of the PKY series power modules is achieved mainly by conduction from the baseplate to a heatsink (“cold wall”). If the baseplate temperature is kept below +100°C, the module can deliver full output power at ambient temperature up to +85°C without forced airflow cooling. The PKY series power modules can also operate without a heatsink but sufficient airflow must be provided. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at V in = 27 V. The DC/DC converter is tested on a 254 x 254 mm, 35 μm (1 oz), 8-layer test board mounted vertically in a wind tunnel with a cross-section of 305 x 305 mm. Proper cooling of the DC/DC converter can be verified by measuring the temperature at positions P1…P5. The temperature at these positions should not exceed the max values provided in the table below. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to T ref +100°C. See Design Note 019 for further information. Position Device Designation max value P1 PCB 125º C P2 Transformer M1 120º C P3 Baseplate Tref 100º C P4 Diode D15 120º C P5 MOSFET T16 120º C Definition of reference temperature (Tref) The reference temperature is used to monitor the temperature limits of the product. Temperatures above maximum Tref are not allowed and may cause degradation or permanent damage to the product. Tref is also used to define the temperature range for normal operating conditions. T ref is defined by the design and used to guarantee safety margins, proper operation and high reliability of the module. Calculation of the Maximum Ambient Temperature By using the thermal resistance the maximum allowed ambient temperature can be calculated. 1. The power loss is calculated by using the formula ((1/η) - 1) × output power = power losses (Pd). η = efficiency of converter. E.g 94 % = 0.94 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Calculate the temperature increase (ΔT). ΔT = Rth x Pd 3. Max allowed ambient temperature is: Max Tref - ΔT. E. g. PKY 2616 PI at 1m/s: 3. 100 °C - 73°C = max ambient temperature is 27°C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow. The above calculations of the maximum ambient temperature are based on the thermal resistance of the PKY module without a heatsink. 0.94 E PKY 2000 PI series DC/DC converters, Input 18-36 V, Output 21.5 A/600 W EN/LZT 146 385 R2B March 2011 © Ericsson Power Modules AB Technical Specifi cation
