I have done some more work today on the current amplifier and found that I did not have the input turned up to a high enough voltage to obtain the full 1A output, so I have now repeated the test and monitored the heat output from the amplifier.   This is still just within the nominal operating temperature specified for the op-amp, but it was still climbing slowly when turned off. When switched back down to a 0.5A output, the temperature does start to drop away quite rapidly.   With ...
I haven't had much chance to work on the clamp table this week so it isn't quite complete, the majority of the time has been spend building and testing the current amplifier after the PCB had arrived.   For the clamp table,  I have cut some wooden legs for it and fitted them but they will need painting before final assembly. I have cut and profiled a base board for the table to sit on, this received a final coat of paint today, that is currently drying.  Five rubber feet will fin ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   IntroductionFor my entry in the electromagnetism contest, I decided to look at building some current clamp table adapters. The intention of these was to allow me to test the full-scale range of current clamps utilising my single phase injection test set. I also intended to look at trying to test the frequ ...
