Default Give me some facts for DC Regulated POwer Supplies

Hi everyone. I have been looking at DC regulated power supplies for my various planes, but also to power some other devices . I know about used computer PS, but I prefer a dedicated PS in metal case, with volt and/or amp meters.

Do you think a fixed 13.8v DC... or a 6v to 15v variable ? I have been looking at several Pyramid regulated power supplies. What do you think? Any advice is appreciated. Good flying. Mike

I just picked up a variable power supply from Circuit Specialists. 0-15V/0-30A, for $120. The advantage of a VPS over a fixed is that you can use it for things like motor testing - if you're trying to determine thrust at a particular voltage, for example, rather than trying to catch it as a lipo drops. So far this has been a solid unit, I'm happy with it.

Thank you bsoder. I like your info. I will look at the one you recommended. Are the VPS safe?

Mike,

The Pyramid Brand has a good reputation as a 'Hobby power supply', you can pick up some excellent 'Industrial Grade' PSU's on Ebay, sometimes for a fantastically low price. I snagged a Tenma 0~15 Volt 30 Amp unit for $20.

I finally broke down and bought a Pyramid 36 amp unit on E-Bay with both volt/amp meters and adjustable voltage 12-15 volts. Have it wired to seven 12 volt outlets on my charging bench. I could not be happier with this set up.

Here are my setup's one for home and the other for the field. The Field Box has a 25Amp PSU in the bottom of the box giving me the option to use mains or battery to power the 3 output distribution box (our club house has mains power).
