Sonel S-50 DC High Voltage Insulation Tester
Index: WMGBS50DC
Description
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.
Sonel offers online training course on the use of this product (instructional video and consultation with a specialist).
