S-25DC

Description Technical Specification Download Files

MV and HV insulation under full control

The S-25 DC device is universal high voltage tester. 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.

S-25 DC stands out in particular. Not just with modest dimensions. Thanks to an internal rechargeable battery it enables mains-independent testing.
