ACREL Three Phase CT Energy Meter with RS485 Modbus RTU
ACREL Three Phase CT Energy Meter with RS485 Modbus RTU is a DIN rail mounted multifunctional energy meter designed for three-phase electrical measurement and monitoring. It measures voltage, current, active power, reactive power, apparent power, power factor, frequency and electrical energy, with support for bidirectional active and reactive energy measurement. RS485 communication with Modbus RTU allows the meter to exchange measurement data with compatible monitoring, inverter and energy management systems.
The ACREL Three Phase CT Energy Meter with RS485 Modbus RTU is a three-phase DIN rail energy meter designed for measuring and monitoring electrical parameters in new energy and power distribution applications. The meter can be used with external current transformers and supports three-phase four-wire, three-phase three-wire and single-phase three-wire measurement configurations according to the manufacturer's published specifications.
It measures voltage and current together with active, reactive and apparent power, power factor and frequency. The meter also supports forward and reverse active and reactive energy measurement, making it suitable for systems where energy can flow in both directions.
The RS485 interface uses Modbus RTU communication, allowing measured information to be integrated with compatible monitoring equipment, inverters or energy management systems. The DIN rail format provides a practical installation method for electrical control cabinets and distribution equipment.
