Need to get MG Electronics Power Supply repaired...or NOT!?

Former Member

Hi.

I just bought a lot of Slot Car stuff, yes those cars that go around a track. The guy was serious about his hobby he didn't have the usual wall plug in power pack, he used a MG Electronics PS-10AD, 0-20 VDC at 10 Amps. Well this power supply doesn't work anymore. It does turn on and the red overload light stays on. It doesn't put out anything. I used my multimeter etc., nothing. I know that these are made overseas . They did retail for about $200. So the questions is were can I get it repaired OR should I ? I'm in Western MAss.

I did check the fuse , it's fine. I've got a heavy door stop on my hands, it does have a nice handle and cord on it !

Many thanks for info, Ted

    Hi Ted,

    It is probably something simple but you will need to have someone who can open it up and step through the circuit. If you open it up and take some pictures or if you happen to have a schematic we might be able to guess some possibilities. Since there are likely mains voltages (120 Volts AC) at some points inside the case do not mess with it unless you have experience. You might check with the parts suppliers in your area as they might know a tech that can work on it.

    There isn't anything that I know of around here in the sticks that could help me. I'm going to open it up if I can and stay far away from those capacitors. I did go to an electronics school 25 years ago, didn't enter the field, so I know some....just enough to get me into trouble ! I don't remember how to discharge a capacitor, probably just find a good ground with a thick wire...anyhow.

    I'll try snooping around the interwoven , maybe I can find the schematic online. I don't even have a manual that goes with it. I did call MG for a manual. All they really do is import them, nothing else.

    Thanks, Ted

    Hi Ted,

    Likely all the Mains voltage will be on the primary side of the transformer. The caps are probably filtering the secondary voltage and regulated voltage and would therefore have less than 30 or 40 volts on them. I would be glad to look at it for you but I am away from my shop until the middle of April. Book Mark our conversation and if you haven't resolved it by April drop me a reply. I am in Wisconsin so only 1/3 continent away.
