Power Supply with an output voltage of 54V, power of >600 W

Request Number N280851
Need details

Siemens seeks manufacturers of high quality power supplies specifically with an output voltage of 54V, power of >600 W and able to operate indoors at varying temperatures. More specifications listed below. 



We are looking to source an external power supply as a companion product to a product under development and to offer this to our customers within our own product portfolio. 


Key Success Criteria

The requirements for the power supply:

Input Voltage - 120VAC/240VAC nominal.  Ideally 100 VDC to 300 VDC &  88 VAC to 264 VAC

Nominal Output Voltage -  54V.  Could also be 48V if able to adjust up to 54V.

Output Isolation -  1500VAC/2250DC to chassis - A POE power supply requires the same isolation as Ethernet copper media. 

Power output - >=600W  ~12Amp

Industrial Temperature Range - Ideally -40 - +85C, smaller range negotiable

Humidity: up to 95% non-condensing

No moving parts, e.g. ventilator

Mountable in 19” rack/cabinet

Compliance standards – The product shall support humidity from 95% (non-condensing) at 55C for a period of 96 hours. (IEC 60068-2-30)


  • Conformal coating 
  • The following approvals:
    • IECEx for Zone 2
