Sonel WMUSS25DC High Voltage Insulation Tester S-25 DC

HV insulation under full control

The S-25DC device is a universal high voltage tester. It stands out in a special way. Not only by its modest dimensions. Due to its internal rechargeable battery, it allows tests even when mains power is unavailable.

Capacitive objects, such as shielded power cables, will be correctly and automatically discharged by the integrated discharge module if an error occurs or the test time expires. A key switch, a switch-on lock and a protective earthing circuit ensure maximum safety.

Sonel offers online training course on the use of this product (instructional video and consultation with a specialist).
