SDM320C Single Phase Multi-function Remote Control Energy Meter for Energy System
Description:
The SDM320C is a single phase multifunction remote control direct connect meter. It has a built-in relay, you can remote control turn on or off when you work in front of computer. Besides, it has alarm system, the relay will open automatically when the parameter reachs the alarm value. There are 26 types alarm object and alarm value you can set by rs485. SDM320C measures and displays the characteristics of single phase two wires (1p2w) supplies, including voltage, current, frequency, power, active and reactive energy, imported and exported. Energy is measured in terms of kWh, kvarh. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product.
SDM320C supports max. 100A direct connection, saves the cost and avoid the trouble to connect external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces provides pulse and RS485 Modbus RTU outputs. Configuration is password protected.
