At my current data center, 400/230V is delivered to the racks. Is their any way I could step this down to 120V without a transformer? I'm trying to see if maybe there is a PDU that exists that can do this for me. The power receptacle is L22-20 and cannot be changed to L21-20.

Any tips or ideas on whats the best solution here?

Thanks

  • Sorry, why you need that? Every power supply I have seen in the last 10 years for even cheaper computer equipment handles 110 to 250 volts and thus can handle both voltages.

Unless you're running fans or something similar every piece of equipment going into that rack will have a switchmode power supply. If one of those power supplies doesn't accept the typical 90-260VAC it will probably be cheaper and easier to replace that individual PSU.

As to if a product exists (which will be a transformer in some part) there may be an online/dual conversion UPS that could support both voltages. I haven't come across one though. There are dedicated voltage and frequency converters you can buy, but again those are transformers.
