#188193 - "Suddenly" ? Responding to: ???'s previous message |

I've been using an old Farnell Type E350 lab supply (0 to 350V at 0 to 200mA) which has suddenly stopped producing full output volts. What, exactly, do you mean by, "suddenly"? If it had been working, then you switched it off, then the problem appeared when you switched it back on - that could be something that go over-stressed due to the startup "inrush"... Electrolytic caps would be worth a close look... |
