BEA-646
460 Watt
- High-quality electrolyte capacitors (+105 °C)
- Ball-bearing fan with tacho signal
- Designed for continuous operation 24/7
The 460 W PC power supply BEA-646 is distinguished by very high reliability, robustness and long service life. Designed for continuous operation (24/7) its MTBF is 87 000 h at +50 °C operating temperature. The 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.

During a cross regulation test we recommend to keep the channel with higher output load at 90 % of its max. power and the channel with lower output load at 20 % of its max. power. 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.
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.
