Introduction
The SDM530C is a three phase multi-function remote control energy meter. It measures all
important electrical parameters, such as Active Energy (kWh), Current (A), Voltage (V),
Frequency(Hz), Power Factor, Power Demand, import and export energy etc. With built-in relay
inside, the meter can be remotely controlled to turn on or off the electricity supply via RS485.
The user can also set alarm objects and alarm level, once the alarm is activated the relay will be
turned off.
