BEA-640
400 Watt
- Noise immunity for industrial sectors
- High-quality electrolyte capacitors (+105 °C)
- Designed for continuous operation 24/7
The 400 W PC power supply BEA-640 is distinguished by very high reliability and long service life. By its integrated 4 kV surge input filter the BEA-640 is also suitable for highly demanding industrial applications. Within an ambient temperature range of -10 up to +50 °C full power can be supplied continuously without restrictions. The temperature regulated ball-bearing fan provides a tacho signal and can continuously be monitored by the board, which is very important with regard to system reliability.

Max. output is 400 W, combined max. output current at +3.3 V and +5 V must not exceed 45 A. For temperatures <20°C a higher minimal output current is required. Ripple and Noise was measured by a 20 MHz bandwidth limited oscilloscope with connected 220 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.
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.
