Multi-Channel Electronic Energy Meter
CED-4C ML
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.
