The ST 3820L surge testing device was specially developed for integration into automatic testing systems. It is excellent to detect winding shorts and insulation faults within a winding, even before the fault is detected in the electrical specifications of the DUT. 

Modern – efficient – intuitive 

The ST 3820L can be controlled via Ethernet (LAN) without any problems or interference. Combined with our DAT remote control software, you will receive a full quality system with 4 decades of experience in testing technology. Alternatively, we would also be more than happy to support your customised software development with a DLL that can be provided as an accessory. It has never been such child’s play to carry out a shorted coil test yourself.

Ready to use anytime and anywhere

The 19"/ 3 HE slide-in unit can be integrated into any testing system – even afterwards. You only need a 115 V / 230V power supply and the testing can begin!
