Many applications require a 110VDC power source.

Although MEAN WELL does not manufacture many power supplies with a 110VDC output, you can simply place two 48V power supplies in series and adjust the voltage up to 55v each. 

We recommend that you add diodes externally to prevent any risk of reverse voltage damage, as per the following 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.

Most applications win Australia require a DIN rail power supply. 

The 48V models of MEAN WELL NDR, SDR, TDR, and WDR series DIN rail power supplies can all be adjusted up to 55V. 

Please do not hesitate to contact MEAN WELL Australia, if you have any questions about connecting power supplies in series.
