BES-630V
320 Watt
- +12 VDC input
- Temperature controlled ball-bearing fan
- Temperature range 0…+60 °C
The DC PC power supply BES-630V provides a +12 V DC input to supply computer systems for industrial applications or in mobile systems. Due to its wide input voltage range from 9 to 18 V DC the BES-630V remains unaffected by input voltage fluctuations. Its ambient operating temperature ranges from 0 °C to +60 °C.

Max. output power is 320 W, combined at +3.3 V and +5 V it is 150 W. Ripple and noise was measured by a 20 MHz-oscilloscope with connected 10 µF electrolytic capacitor and 0.1 µF ceramic capacitor at each output. During a cross regulation test we recommend to keep the channel with higher output load at 80 % of its max. power and the channel with lower output load at 20 % of its max. power. From 5 V / >20 A onwards a load of >6 A must be connected at +12.
This power supply is for assembly purposes only and it must not be operated in unassembled condition. The final assembly has to comply with the valid EMC standards.
