The SDM120CT-MODBUS-100MA is a single-phase DIN rail energy meter designed for solar PV and zero-export applications. It uses 100mA input and provides accurate monitoring of electrical parameters including energy consumption, voltage, current, power, power factor, frequency, and reactive energy.
The meter features an RS485 communication port for remote monitoring and configuration, along with two pulse outputs for integration with external systems. It is ideal for use in single-phase solar PV installations.
