![]() ![]() What I was more so unsure of was a bit related to the herts, as differernt countries (Japan, China, Euroupe) use differernt frequencies and I wasnt sure if it would be detrimental to the operation of the power supply. Should be simple enough so long as I dont mix up the power supply selector. So I was thinking of making an adaptor plug or wire that would plug into the 220 receptical and either into my 120 plug or directly to the power supply reciptical. My printer has a standard 120 (or is it 110) northa american 3 pringed plug. The gist of what I was thinking was I have a 220V plug in the wall which i think was ment for a dryer at some time. I’m currently 2 time zones away from my printer, but can send picutres when I get back. The output amperage and voltage of the supply itself will remain unchanged regardless of the voltage setting/supply voltage.Ĭaveat: I’m an 442A Industrial Electrician. There is no difference in efficiency between 120VAC and 220VAC other than the current required to supply the device.Ī 350W draw on a 220VAC system would give you 350W/220V≈1.6A current draw to feed the supply.Ī 350W draw on a 120VAC system would give you 350W/120V≈2.9A current draw to feed the supply. The four power suppies on my CNC machine all have that feature as does my printer. Most power supplies have a switch on the side of the supply case to allow you to select between 120VAC and 220VAC as the input voltage and will run on either 50Hz or 60Hz. ![]() The adapter plug just changes the pins to slots, nothing else. I have a plug with a 220VAC receptical end that came with an adapter plug to allow it to be plugged into a 120VAC receptical. If the plug itself is 220VAC with the round prongs on the plug-into-the-wall end, that means the plug was designed to fit a standard 220VAC outlet but the end that fits into the supply should be standard regardless of the plug type on the receptical end. My key question is: Is it just the plug that is 220 volts or the power suppy requirement? ![]()
