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