Multi-Channel Electronic Energy Meter


For multi-channel measurements, this advanced multifunction energy meter comprises 4 modules within one energy meter. RS485 Modbus Communion is provided through 2 x RJ45 connectors.

About the Product

Providing measurement for multiple channels, this new multi-function electronic energy meter works with a variety of wiring modes and provides a variety of measurements, including voltage, current, power, PF, THD, frequency, demand, energy, and more. Easy to wire and install due to their plug-in connectors, these multi-load meters can be used as 4 x Three-Phase Energy Meters, or 12 x Single-Phase Energy Meters. Required with these meters is the use of 100mA/100mV secondary external Current Transformers. The electronic meter comes with a RS485 communication port through 2 x RJ45 connectors.

Product Features

  • Comprising 4 modules within one energy meter, yet only 72mm in product width – more compact than using 4 x three-phase meters
  • Convenient "easy-click" plug-in connection
  • Current Input: RJ12 100mA
  • Current transformer ratios can be programmed independently (Load 1, 2, 3, 4)
  • Providing measurement of a variety of parameters
  • RS485 RTU Modbus Communication
  • THD of Voltage and Current
  • Quad-Load Option (3P4W x 3, or 1P2W x 12)
