We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Someone came to me just recently to discuss a power supply problem in which one particular diode would fail shorted following a mechanical drop test of the unit. Over and over again this would happen.

Output test points are provided for shunt measurements. The Astrodyne TDI Defender series of ICCP products provides advanced high frequency switching power supplies to the cathodic protection market.
