PS503A max current


Robert Simpson
 

I have a working PS503A in my TM504 right slot. I need a power supply with more than 1 amp at a low 3.3 volts. Can the two independent 20V supplies be run in parallel similar to the way they can be run in series for 40V?

The 20V supplies are not independent and cannot be paralleled. The negative of the positive supply and the positive of the negative supply are common and cannot be separated.

A module such as this could give up to 3 amps at 3.3V from one of the 20 volts supplies: https://www.ebay.com/itm/223524573272
