Voltage presence detectors and indicators are devices used to provide information on the status of voltage presence or absence in the main power circuit in the equipment (switchgear or distribution) and in which they are installed. Three products are available:

A71VDSMR & A71VDSF
Voltage Detecting System (VDS) certified compliant according to IEC 61243-5

A71SMTE/ML & A71SMTE/F
Voltage Detecting System (VDS) according to DY1811 (DY811) approved by ENEL

A71VPIS01
Voltage Presence Indicator System (VPIS) according to IEC 62271-206

Detectors (VDS Voltage Detecting System IEC 61243-5) provide monitored indication of voltage presence, while Indicators (VPIS Voltage Presence Indicator System IEC 62271-206) provide voltage presence indication only
