    Default US split phase 220V power supply question

    I live in North America and use split-phase 220V where I can in my shop. I am looking to source a 24VDC power supply, and managed to get myself confused. Most of the DIN mountable power supplies I see that claim 110V/220V compatibility are single phase devices (labeled L and N), such as https://www.mouser.com/datasheet/2/2...ec-1109663.pdf. I assume I can't (or shouldn't) plug my 220V (both hot wires) into that right?I guess I can stick with a 110V PS, but was trying to simplify my setup since I need 220V for my VFD.

    Speaking of my 220V VFD (Haunyang HY01D523B). I assume I am ok using my split-phase power into that. I would just connect both hots into the R and S terminals, and leave T unconnected.

    In N.A. the voltage is really 240V/120V or sometimes called 230V/115V, just depends on the label on the device. Many times your actual line voltage could be as high as 245V or so, it's all the same and works fine.

    For the 24VDC power supply, if you choose to wire it at 240V just connect one hot to each of the power in terminals. They may be labeled L and N, just make sure the PS is rated for 240V (220) input voltage.

    Yes, for the HY VFD, just connect the 2 hots per the manual.
