Due to its + 24 V DC input, the 420 W ATX BEH-542C power supply is the ideal power supply for computer systems used in automation or mobile systems. Due to its wider input from 18 to 36 V DC, it is not affected by input voltage fluctuations. The BEH-542C is designed for an operating ambient temperature range of -20 to + 70 ° C
As a power component, this power supply is for mounting purposes only and should not be operated under unassembled conditions. The final assembly must conform to valid EMC and safety standards.

  • Input + 24 VDC.
  • Wide input range.
  • Lines + 3.3 V and + 5 V.
  • Ball bearing fan.
  • Wide operating temperature range -20 ~ + 70 ° C.
  • No minimum load is required.
  • Designed for continuous operation 24 / 7!

Max. output is 420 W, the combined output current of + 3,3 V and + 5 V must not exceed 170 W. Ripple and Noise were measured by a limited 20 MHz bandwidth oscillator with 220 tantalum capacitor μF and 0,1 μF ceramic capacitor at each outlet. All measurements were taken at + 21 ° C at room temperature. The data may differ at startup when the room temperature is below 0 ° C. To maintain the interference conducted according to the EN55032 standard (in the case of connection to a low voltage electrical network), an additional input filter may be necessary .
As a power component, this power supply is for mounting purposes only and should not be operated under unassembled conditions. The final assembly must comply with the valid EMC and safety standard
