Power Cycling test systems & IOL

Efficient testers with modular system for fast scalability

High measurement quality at high throughput. Permanently increase the effectiveness of your reliability tests with a power cycler or IOL test system.

Low Total Cost of Test (TCOT)
with high quality and high throughput

SET’s power cyclers and load cycling test systems, or IOL (Intermittent Operating Life) test systems, efficiently test power semiconductors. When testing with a power cycler, the DUTs are switched on and off continuously, thus thermally stressing the DUTs. Power cycling test systems increase measurement quality and throughput and reduce testing costs on an open platform. The focus is on seamless moni­toring and precise determination of all parameters of each DUT.

In addition, the systems are equipped for the special requirements of wide bandgap technology and are compatible for a measurement with the materials SiC and GaN.
