Modular Test System ST400

The modular electrical safety tester ST400 can be fitted with diferent test modules such as high voltage, insulation, protective earth, leakage current, function test and many more. Due to this flexibility the tester can perform a great number of norm tests for example VDE, EN or UL norms.

The safety tester can be both remote controlled and operated directed on the device. Depending on the application the ST400 can be supplied with different operating variants. Available are 2 TFT touch displays in different sizes and a remote version without a own display. A complete industrial PC can be integrated as well to replace a PC for the test system. The tester has both optional USB and LAN interfaces to store result data and test plans on a USB Stick and in the local network.

There are several different drivers available to realize a complete remote control. The drivers and libraries include LabView, DLL, ASCII, .NET-Framework and Active-X. The driver packages also include programming support from our staff to help implement the ST400 in your test system.

The wide range of accessories includes both a wide range of adaptation options, as well as trolley and safety accessories.
