The DC PC power supply BES-540C has been designed for use in
industry, logistics and transport. Thanks to its broad input voltage
range of 20 to 36 V DC it is immune to high input voltage fluctu-
ations. With a high output power load of +12 V DC it is capable
of safely supplying the necessary power for high-performance
graphic applications. The fan on roller bearing is temperature
controlled and provides a tachometer signal for monitoring.
* A total minimum base load of 10 W is required.
Max. output power is 400 W, combined max. output power at +3.3 V and +5 V is 35 A. Ripple and Noise was measured by a 20 MHz bandwidth limited oscilloscope with connected 220 µF
electrolytic capacitor and 100 nF ceramic capacitor at each output.
As a power component this PSU is for assembly purposes only and must not be operated in unassembled condition. The final assembly has to comply with the valid EMC and safety standards.
