It's a Weir SMM 300 SV multiple output power supply!
The input is 115V and the out puts are two 5V, two 15V, one 24V and one 12V.
Power supply was used to power a small display that had different voltage needs for some small motors for exactly 9 hours during a convention.
Unit was purchased 100 percent new and as always with anything we sell it will be tested again before shipping with a video showing the power out puts on a DVM.
THERE WILL BE NO RETURNS, NO REFUNDS, NO WARRENTY WHAT SO EVER.
So if you have questions you need need to ask before buying.
