PWR-DC-VOLTDC Voltage & Failure Sensor
12-80 VDC — positive or negative polarity
for telecom plants & battery systems

Continuously measures the DC bus from 12 to 80 VDC.
Positive or negative polarity — -48V telecom plants natively.
Voltage measurement and failure alarm in one sensor.
Threshold alerts turn a sagging bus into an early warning.
Immediate alerts via email, SNMP traps & optional SMS.
Plug & play on the base unit — no PC or software required.
BMS ready via Modbus TCP, BACnet IP & Modbus RTU.
SNMP for NMS/DCIM & MQTT for IIoT.

PWR-DC-VOLT DC voltage and failure sensor

At a glance:
Range: 12-80 VDC
Polarity: positive or negative
Output: live voltage + failure alarm


Voltage & Failure in One

A failure sensor tells you the power died. This one also shows the voltage sagging on the way down — and coming back up.

-48V Telecom & DC Plants

Positive or negative polarity across 12-80 VDC: -48V telecom plants, 12/24/48V battery systems and DC distribution, natively.

From Float to Failure

Staged voltage thresholds turn a battery discharge into a countdown with warnings — instead of a single alarm when it's already over.

Where to Install

Rectifier outputs, battery bus bars, DC distribution and remote cabinets — the points where the bus voltage tells the site's story.

Alerting & Integration

Live voltage and failure status with immediate alerts via email, SNMP traps & optional SMS — straight into your BMS over Modbus TCP, BACnet IP or Modbus RTU.
