Description Technical Specification Download Files

HV insulation under full control

The S-50 DC device is universal high voltage tester. It is extremely robust, but also lightweight, compact and easily portable thanks to a transport case on wheels. Capacitive loads, such as shielded power cables, will be properly and automatically discharged in case of an error or at the end of testing time by the integrated discharge device.

Key switch, switch-on interlock and a protective ground circuit ensure maximum safety.
