Power Supply Unit * [ TYPE : PS 402 ]
Technical Data
Power Supply PS402 designed for mating with NIM Instrumentation Bin IB402, offers a complete rack mountable assembly or can be housed for table-top use. The D.C. output voltages furnished by PS402 are +12V and -12V at upto 3A each and +24V and -24V at upto 1.5A each. A 115V a.c. power output is also distributed to the Bin. Power Supply PS402 is overload and short circuit protected and has excellent load and line regulation with low ripple.
Features
Specifications
| Input | 117V / 230V AC, single phase 50Hz with 10% variation in input voltage range. 3 Pin MS series connector is provided through 3-core cable. |
|---|---|
| DC output | +12V DC at 3A; -12V DC at 3A +24V DC at 1.5A; -24V DC at 1.5A total output load not to exceed 96W at 30o centigrade |
| AC output | 115V AC @0.5A has been wiredup and provided at each of the module connectors. |
| Regulation | Better than +/-0.05% over combined range of zero to full load and input voltage of 88% to 110% of rated input at constant ambient temperature after a 60 min warmup. |
| Stability | After warmup the voltage shall not vary by more than +/-0.2% of the nominal values at any time during any 24 hours period at constant ambient temperature over the combined range of no load to full load and input voltage 10% to -12% of nominal |
| Temperature Range | 0 oc to 50oc without derating. Operation upto 60oc is possible with a derating of 3% per oc for temperatures above 50oc. |
| Temperature Coefficient | Less than 0.02% pero upto 50oc. |
| Noise & Ripple (rms) | The combined output voltage noise and ripple shall not exceed 5mV |
| Voltage Adjustment | Output is adjustable over a nominal range of atleast +/-0.5% by means of a screw driver adjustment. Adjustment potentiometers are provided on the PCBs and are easily accessible when top cover is removed. |
| Circuit Protection | a. Input of the mains supply is protected by two fuses. b. Overload and short circuit protection is achieved by electronic circuitry. The output shall recover automatically when the overload / short circuit is removed. Continuous short circuit will not damage the power supply |
| Dimensions | 430W x 168D x 153H approx. (in mm) |
