CT5.121 C-Series 12V, 8A, TWO-PHASE INPUT POWER SUPPLY AC 380-480V Wide-range Input Input Fuses Already Included Requires only Two Legs of a 3-Phase System Width only 40mm Efficiency up to 85.8% Input -Transient Blanking Circuit Included Minimal Inrush Current Surge Full Power Between -25°C and +60°C 3 Year Warranty GENERAL DESCRIPTION The Dimension C-Series are cost optimized power supplies without compromisi ng quality, reliability and performance. The C-Series is part of the DIMENSION power supply family. The most outstanding features of CT5.121 are the high efficiency, electronic inrush current limitation, active input tr ansient filter and wide operational temperature range, the small size and other technological design concepts. The C-Series includes all th e essential basic functions. The CT5.121 utilizes only 2 legs of a 3-phase system which saves wiring and installation costs. Furthermore, this allows a smaller unit without compromising the size of the terminals. Due to the low power consumption, an unbalancing of the individual phases is not expected.

CT5.121 C-Series 12V, 8A, TWO-PHASE INPUT 23. APPLICATION NOTES 23.1. PEAK CURRENT CAPABILITY Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state current and usually exceeds the nominal output current (including the PowerBoost) The same situation applies, when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in the branch circuit, the fuse needs a certain amount of over-current to trip or to blow. The peak current capability ensures the safe operation of subsequent circuit breakers. Assuming the input voltage is turned on before such an event, the built-in large sized output capacitors inside the power supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following two examples show typical voltage dips: Fig. 23-1 Peak load 16A for 50ms, typ. Fig. 23-2 Peak load 40A for 5ms, typ. 10ms/DIV Output Voltage Output Current 12V 16A 1ms/DIV Output Voltage Output Current 12V 40A 3.7V Peak load 16A (resistive load) for 50ms Output voltage dips from 12V to 7V. Peak load 40A (resistive load) for 5ms Output voltage dips from 12V to 3.7V. 23.2. BACK-FEEDING LOADS Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force). This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter, whether the power supply is on or off. The maximum allowed feed-back-voltage is 25Vdc. The absorbing energy can be calculated according to the built-in large sized output capacitance which is specified in chapter 6.

CT5.121 C-Series 12V, 8A, TWO-PHASE INPUT 23.3. CHARGING OF BATTERIES The power supply can be used to charge 12V lead-acid or maintenance free batteries. Instructions for charging batteries: a) Ensure that the ambient temperature of the power supply is below 45°C b) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage. End-of-charge voltage 13.9V 13.75V 13.6V 13.4V Battery temperature 10°C 20°C 30°C 40°C c) Use a 10A circuit breaker (or blocking diode) between the power supply and the battery. d) Ensure that the output current of the power supply is below the allowed charging current of the battery. e) The return current to the power supply (battery discharge current) is typ. 5.5mA when the power supply is switched off (except in case a blocking diode is utilized). 23.4. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 30A (U.S.A.) and 32A (IEC). An external protection is only required, if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local regulations might apply. If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit breaker. A minimum value of 6A B- or 3A C-Characteristic breaker should be used 23.5. INDUCTIVE AND CAPACITIVE LOADS The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

CT5.121 C-Series 12V, 8A, TWO-PHASE INPUT 23.6. PARALLEL USE TO INCREASE OUTPUT POWER CT5.121 power supplies can be paralleled to increase the output power. This power supply has no feature included which balances the load current between the power supplies. Usually the power supply with the higher adjusted output voltage draws current until it goes into current limitation. Therefore, the power supply can only be used in parallel as long as the ambient temperature stays below 45°C. The output voltages of all power supplies shall be adjusted to the same value (±100mV). A fuse or diode on the output of each unit is only required if more than three units are connected in parallel. If a fuse (or circuit breaker) is used, choose one with approximately 150% of the rated output current of one power supply. Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power supplies on top of each other. Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation (input terminals on the bottom and output terminals on top of the unit) or in any other condition where a derating of the output current is required (e.g. altitude, above 60°C, …). Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. Unit A AC DC Unit B AC DC Load 23.7. PARALLEL USE FOR REDUNDANCY Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the other one is automatically able to support the load current without any interruption. Redundant systems for a higher power demand are usually built in a N+1 method. E.g. six power supplies, each rated for 8A are paralleled to build a 40A redundant system. For N+1 redundancy the same restrictions apply as for increasing the output power, see also section 23.6. Please note: This simple way to build a redundant system does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a case, the defect unit becomes a load for the other power supplies and the output voltage can not be maintained any more. This can only be avoided by utilizing decoupling diodes which are included in the decoupling module YR2.DIODE. Recommendations for building redundant power systems: a) Use separate input fuses for each power supply. b) Monitor the individual power supply units. c) 1+1 Redundancy is allowed up to an ambient temperature of 60°C N+1 Redundancy is allowed up to an ambient temperature of 45°C d) It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

CT5.121 C-Series 12V, 8A, TWO-PHASE INPUT 23.8. DAISY CHAINING OF OUTPUTS Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block. Fig. 23-3 Daisy chaining of outputs Fig. 23-4 Using distribution terminals Power Supply + + - - Input Output Load + - max 25A! Power Supply + + - - Input Output Load + - Distribution Terminals Power Supply + + - - Input Output Power Supply + + - - Input Output 23.9. SERIES OPERATION Earth Unit A AC DC Unit B AC DC Load Power supplies of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are not SELV any more and can be dangerous. Such voltages must be installed with a protection against touching. Earthing of the output is required when the sum of the output voltage is above 60Vdc. Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals. Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power supplies on top of each other. Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. 23.10. USE IN A TIGHTLY SEALED ENCLOSURE When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the power supply. The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure. The power supply is placed in the middle of the box, no other heat producing items are inside the box Enclosure: Rittal Typ IP66 Box PK 9516 100, plastic, 110x180x165mm Load: 12V, 6.4A; (=80%) load is placed outside the box Input: 2x 400Vac Temperature inside enclosure: 51.1°C (i n the middle of the right side of the power supply with a distance of 2cm) Temperature outside enclosure: 25.2°C Temperature rise: 25.9K Jan. 2010 / Rev. 1.0 DS-CT5.121-EN All parameters are specified at 12V, 8A, 400Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany

MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximal allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Recommended output current. Curve A2 Max allowed output current (res ults in approximately half the lifetime expectancy of A1).
