Product information "VOIS R+"
The VOIS-R is an integrated Voltage Detecting Systems VDIS for checking for absence of voltage in medium voltage switchgear according to IEC 62271-213:2021 (or IEC 61243-5) with integrated three-phase continuous indication as well as a signalling contact.

Voltage indication system for medium voltage (VDIS)

Integrated three-phase voltage indication system for medium voltage switchgear acc. IEC 61243-5 and IEC 62271-213

Relay output

changeover contact for status indication

No battery required

Voltage indication without battery or auxiliary voltage

Integrated three-phase measuring point

The device has a three-phase LR measuring point for phase comparison, rotating field direction measurement, etc.

Convenient alternative

to plug-in voltage indicators.
