The AC Voltage Sensor is used to indicate the presence or absence of line voltage. This is useful, for example to tell when the UPS is running on battery power.

The AC Voltage Sensor indicates an ALARM/NORMAL condition in software and also via an LED mounted on the sensor. Voltage detectors can detect the presence or the absence of line voltage. It is designed for use worldwide. There is an SNMP interface for getting the alarm/normal status. SNMP traps are sent when critical conditions occur.

SNMP polling via ‘get’ is available to retrieve existing status and configuration parameters. The Web browser interface is also available to display the status and configuration parameters.

When an alarm condition is activated the description and location of the fault can be sent via email, page or traps.
