Product specific data
Sound level <35 dB(A)
The BEL-540H has a very effective and temperature-controlled
fan regulation, which reduces noise levels to a minimum.
Due to its very low standby power consumption of less than
0.5 watts the industrial PC power supply meets the ECO
standard ErP directive 2009/125/EG. The innovative circuit
design ensures excellent voltage regulation and high efficiency
with „80 PLUS® Bronze“ certification.

*Peak output power is max. 440 W for 1 second.
Max. output power is 400 W, combined output power at +3.3 V and +5 V must not exceed 130 W. Combined output current at 12 V1 and
V2 must not exceed 30 A / 360 W. Ripple and noise was measured by a 20 MHz oscilloscope with connected 10-µF- + 100-nF capacitor at
each output. 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.
