eGauge High Voltage Sensor (EV1000)

 Visit the online store page
Model: EV1000

Requires the eGauge Sensor Hub and eGauge model EG4xxx (Pro or Core), not compatible with older model units.

Only use straight-through RJ-11 cables to connect powered sensors to the Sensor Hub. Telephone systems generally use "reverse" style RJ-11 cables which are incompatible with the Sensor Hub. See this article for more information on verifying the correct RJ-11 wiring. Every Sensor Hub compatible sensor sold by eGauge Systems comes with a straight-through RJ-11 cable.

The eGauge High Voltage sensor is used in conjunction with the Sensor Hub and an EG4xxx model meter (Core or Pro) which allows EG4xxx meters to read voltages up to 1,000 VDC or 707 VAC.

Assembly/installation information

The high voltage inputs to the EV1000 can be connected Line-to-Line or Line-to-Neutral as long as the voltage potential does not exceed 1,000 VDC or 707 VAC. Safety grounds cannot be used for voltage measurements.

Connection to EG4xxx Meter

  1. It is not advisable to extend the RJ11 leads from the Sensor to Sensor Hub. It is acceptable to use a longer RJ45 cable from the Sensor Hub to the eGauge.
  2. If RJ11 cable between Sensor and Sensor Hub must be extended, it is advisable to use twisted pair wires, such as a CAT5 cable with RJ11 plugs (most commonly used for DSL modems).
  3. If terminating own cables, both RJ11 and RJ45 cables should be straight-through cables, with the same color order on both ends.
  4. See Installation Examples for common use cases of the EV1000.

  1. Install the sensors and Sensor Hub.
  2. Connect the EV1000 to a voltage reference no greater than 1000Vdc or 707Vac.
  3. Configure the sensors.

Connection to non-eGauge meter inputs

Use the 4-pin connector next to the RJ11 port. +5 VDC and ground is required to power the sensor.

SIG+ and SIG- output a ±5V signal proportional to the line inputs.
