How to test a driver?

[Mattbho]

Scored this bad boy fir 20$ at the bin store . Want to know if it works BEFORE buying leds . I have a few digital testers with ohm amp volt ect .

120v Canadian plug has 3 wires white black ground
So I think it wires like this on Input side
Black to brown (acL)
White to blue (acN)
Ground to ground

Output im unsure of . I know i could get dc voltage . With these red and black. But I think I have to move one for amps

I would be very careful with that because someone may have discarded it. due to problems.

they either work or they don’t

Output im unsure of . I know i could get dc voltage

use a multimeter to test the out put. VDC

if it works it works


if it doesn’t its DEAD

Yeah, with black&white, the black is often live.

Ok fingers crossed ill test it out this weekend .

120 ac to 48v dc . I guess I scored !!!

To check amps you could use a 10A fuse (or even blow the fuse in your multimeter, if you have a spare), but if it gave you 48V, there is 99% chance it will work. Cause the voltage regulation part is the most sensible part of it, so if it works, i would consider it good.
