ACREL Single Phase DIN Rail Energy Meter with External CT and RS485
ACREL Single Phase DIN Rail Energy Meter with External CT and RS485 is a single phase AC energy meter designed for electrical energy measurement and power monitoring using an external current transformer. It measures key electrical parameters including voltage, current, active power, reactive power, apparent power, power factor and frequency. With RS485 communication using the Modbus-RTU protocol, it can connect with an inverter or energy management system for data monitoring and management. The meter supports 80A, 120A, 200A and 300A current options and is suitable for applications such as photovoltaic systems, micro-inverter systems, energy storage and AC coupling systems.
The ACREL Single Phase DIN Rail Energy Meter with External CT and RS485 is a single phase AC energy meter designed for monitoring electrical energy and power parameters through an external current transformer. It is intended for applications where electrical consumption, generation or power flow needs to be measured and communicated to a monitoring or energy management system.
The meter measures voltage, current, active power, reactive power, apparent power, power factor and frequency. It also supports bidirectional active energy measurement, allowing forward and reverse energy to be monitored.
RS485 communication with Modbus-RTU allows the meter to exchange measurement data with compatible monitoring equipment, inverters and energy management systems. Acrel lists applications including photovoltaic grid-connected systems, micro-inverter systems, energy storage systems and AC coupling systems.
How it works
- The meter measures the single phase electrical supply and uses an external current transformer to measure the load current.
- It calculates and monitors electrical parameters including voltage, current, power and energy.
- Forward and reverse active energy can be measured for applications where energy may flow in either direction.
- Measurement data can be transmitted through the RS485 interface using Modbus-RTU.
- The meter can therefore be incorporated into compatible energy monitoring or management systems.
