110VDC Output possible with MEAN WELL DIN Rail Power Supplies


We are often asked if it is possible to get 110VDC output from a DIN rail power supply.

The answer is yes you can.

You simply place two 48V power supplies in series and adjust the voltage up to 55v each.

Mean Well SDR and WDR Series Power Supply in series








Both the MEAN WELL SDR series and MEAN WELL WDR series DIN rail power supplies can be adjusted up to 55V.

ADM recommends that you add diodes externally to prevent any risk of reverse voltage damage, as per this diagram. 

When using DIN rail power supplies in series, one supply may start before the other. The power supply that is slow to start will have a reverse voltage across its output terminals until it starts up. This reverse voltage could damage the components in the output stage if there is no reverse voltage protection.
