Avalanche Extension - Unclamped inductive switching/load ( UIS / UIL )
EFFITEST series allows avalanche measurements UIS/UIL for measuring EAS and EAR. This measurement is specifically designed for production use but it can be of course used also in a laboratory.
EAR and EAS measurements could be performed on a diode, MOSFET, IGBT or bipolar transistors. You can choose from 3 different measuring methods.
Features
- Up to 2500V/100A

The OVP (over-voltage protection)
1) Setting the OVP Level (overvoltage protection threshold ) to 600V
2) Waveform when the overvoltage protection is switched on – no voltage overshoot above threshold (600V)
Acquired waveform
