BES-630C
300 Watt
- +24 VDC input
- Operating temperature -20…+70 °C
- UL508 certified
The 300 W DC PC power supply BES-630C provides a +24 V DC input for powering computer systems applied in automation or mobile systems. It is designed for an operating ambient temperature range of -20 up to +70 °C. Due to its widerange input from 18 to 32 V DC the BES-630C remains unaffected by input voltage fluctuations. Thanks to the softstart function the BES-630C does require no higher inrush current as compared to normal operation.

Combined output power at +3.3 V and +5 V must not exceed 150 W. The +12 V output can supply up to 15 A if + 5 V / 15 A is connected. From a load of 100 W (+3.3 V and +5 V) onwards a minimum load of 1.2 A must be connected at +12 V. Load regulation and voltage regulation were done by changing the measured output load ±40 % from 60 % rated load and all other outputs kept at 60 % rated load. Ripple and Noise was measured by a 15 MHz bandwidth limited oscilloscope with connected 0.47 µF 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.
