![]() ![]() One more thing - the first, 30V 5A one, had a loose bolt rattling inside when i bought it. At the time of a failure it was set to 35V, and there was a brief short circuit. Haven't tried diagnosing it yet since it's past midnight here. Anyone have experience with these or making them more reliable? I'll appreciate any info on this thing, schematics, common failures, etc - these seems to be common all over the world, so someone must have fixed one before. So, is this thing worth repairing? That's about the only sort of power supply that i can buy here, others with comparable specs being almost an order of magnitude more expensive. And then it died less than a month later, giving out 80V! The silver lining is that this time it was honestly reporting that it gives out 80V, instead of showing. Totally expected it to last a few years or more, since it should have less heat and stress. That one worked for a few years, before dying with 50V across it. First time it was HY3005 - 30V, 5A linear power supply. ![]() For the second time a power supply dies on me.
