BEA-635-B1
350 Watt
- Protective paint sealing against short-circuits
- Noise immunity for industrial sectors
- High-quality electrolyte capacitors (+105 °C)
The BEA-635-B1 which is part of the proven industrial PC power supply BEA series can be ordered with a protective paint sealing. In various areas of industry electrically conductive dust particles such as carbon fibres or sooty particles from combustion residues are the reason for short-circuits in electric equipment. As a preventative measure the circuit board, and especially the critical areas in the power supply, are sealed with protective paint. The resulting thin confining layer serves as protection against short-circuit and failure of the power supply caused by this kind of contamination.

Max. output is 350 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.
