Hello to All,
I'm new here and also fairly green when it concerns electronics.
I've been playing around with arduino's and other small stuff, but want to grow and learn more
I've got a couple of Magnetek HPR4915 PSU which came from a couple of old Tally printers from work and since these got multiple DC outputs I thought I could use it as a base for a adjustable bench power supply.
One of the outputs is interesting since it has 40V 3.3A. So this should be more then enough to create a adjustable bench psu. But when I connect it to the mains and start measuring the output wires the maximum voltage I get is 20something Volts...
Could it be that I need to attach some load to get the full 40V?
Regards,
Billie
