product ap300

Application of the AP310 is supported personally by Dr. Ray Ridley, the recognized industry expert in power supply control and magnetics design. If you have trouble making or interpreting measurements, send your test results directly to Dr. Ridley for his insights and analysis. Model 310 adds an isolated USB for increased noise immunity and enhanced signal resolution.

For hands-on training in test and measurement, we recommend attending one of our 5-day power supply design workshops.
