Thread: Power Supply Question

Would this work as a power supply for wiper motors (or other 12VDC motors):

If so, it seems to me like this would be a convenient way to power several props from a single source.

Any thoughts about this??

Yes that would work but I wouldn't use it to power more than two wiper motors. You get the same from a PC Power Supply.

WoW ! Nice find @ a gr8 price...

Just be sure to account for each motors amperage and you should be OK.

Yeah it only drops 10 amps - thats enough for 2.5 motors under load. If you're not pushing much you can get away with 3 motors on that, but like someone else said, a computer power supply does the same thing, and can be gotten for cheaper (free even if you know someone junking an "outdated" computer).

Just an update: I'm working on my own wiper motor as I write this, and I just did some amperage testing.

Under no load, running a wiper motor at 106rpm (high and low connected to 12v) pulled 5 amps to start, then within a second settled down to 3 amps.

Under no load, running high at 12v pulled about 2, down to 1.5 amps.

Under no load, running low at 12v pulled about 1 amp, down to .83 amps.

So under no/light load settings, the amps werent too bad. Easily manageable. It all depends what you're doing with it and how much load its under.

Depending on what you have planned , I think it is a pretty good deal...It's prewired to terminal strips, has individual fused outputs, mounted in an enclosure. I think I'll probably pick up 1or 3 myself.
