I play with electronics a bit. I have at least 5 power rectifiers (as well as battery chargers). First, let me say that the units from Reactive Metals are easy to use and it is a great company. I buy stuff from them from time to time, they have a vast knowledge that they are willing to share, never disappointed. I took a workshop frim Bill Sealy many years ago. With that being said, I think there are some home brew units that are easy and cost effective, A good all around unit with a big voltage range is an isolated power auto transformer like a "Variac or Powerstat' that has built in isolation transformer or an add on one. Mine gives me 0-120 volts at 10 amps. You need to add a simple bridge rectifier and perhaps a capacitor to smooth out the voltage, but you need to monitor the voltage and amperage manually. A couple of my more range limited supplies will automatically control voltage or amperage for better results in a more limited range of V/A. I added a series light bulb to the input of my auto transformer to prevent big fuse blowing shorts. I can short the output and all that happens is that the bulb lights up to limit the power.
