• Takes voltage readings and provides the data to the to the WebMeter36F™
  • Convert the high voltage (up to 600VAC) to a safe milli-volt signal
  • Simple installation
  • Easy connection to the WebMeter36F™


The VoltageSensor™ takes the voltage readings and provides the data to the WebMeter36F™.  It is essentially a Class 1 to Class 2 voltage converter unit that converts the high voltage (up to 600VAC) found in electrical breaker panels to a safe milli-volt signal. These lower voltage levels are presented to the WebMeter36F™ using a simple and easy connection via the built in RJ45 jack.

The enclosure is a flame retardant ABS enclosure with a UL94V-5VA rating. The VoltageSensor™ has UL, ULC, and IEC safety certifications for North America and Europe.
