Chapter 1. Product Overview
1.1 Product Introduction
The SDM320C is a single 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 automatically.
