Thread: Specs for IBM 5150438 XT Power Supply

Quote: Originally Posted by per A step-down transformer should work. You may want one of the older, heavy-duty ones, that simply contains a big induction-coil (as they got the best wave-forms). The frequency shouldn't matter unless the device uses it as timing (No PC, XT, AT, or any other recent computer does this. In fact, there is really few products today that does this at all, as recent TV's are designed to support more than...

I've located an XT PSU with a voltage selector switch but I'm sure the second output will be at the input voltage, so I'm still stuck with the monitor. A step-down transformer should work.

I'll assume that you know for fact that IBM part number 5150438 is an IBM XT (5160) power supply, because I have no information on 5150438. There are 110 Vac and 220/240 Vac versions of the XT power supply. There is a copy of the April 1983 edition of the IBM XT Technical Reference at...

I bought a 220-110V step-down converter in Hong Kong for HK$60 (€5).
