Avalanche Extension - Unclamped inductive switching/load (UIS/UIL)
The EFFITEST series can be extended by the Avalanche option (for UIS and UIL test), for evaluating EAS and EAR parameters. While specifically designed to withstand production environments, it is also well-suited for laboratory use.

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
- Gate driver +/-30V
- Programmable gate resistor 0-1023R
- Programmable over-voltage/current protection up to 2500V/100A - creating parallel energy path for safe discharge
- Possible to set the OVP function - overvoltage protection threshold

Waveform under normal operation
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)
Usable results from the measurement
- EAS, EAR – possibility to choose displayed results
- Detailed waveforms with possibility of easy export to .csv
- Detailed results for EAS (Meas / Calc), IAS Peak, IAS Off, V(BR) Effective, V(BR) Low, V(BR) Peak, dv/dt
