——Product Function——

 

1.Display with LCD display with wide viewing angle and high contrast

2.Communication method:RS485,Infrared,Carrier

3.Apply digital processing technology and SMT process.

4.The main function: measurement and detection, remote fee control , security certification and encryption ,display , event recording , freeze , timing , pulse output, etc.

5.Manganese copper shunt :The current adopts a loop with a highly stable and wide-range manganese copper shunt.

6.Carrier module: Communicate via power line networking without the need for additional cables.

Lora module: long-distance small wireless networking communication.

GPRS module: mobile public network (2G network).

7.Metering chip:A metering chip is used to measure bidirectional active power and four-quadrant reactive energy. The voltage sampling loop adopts resistance voltage division.

8.Optional direct access or transformer access:

Load control can choose built-in or external switch. Built-in switch:

The miniature circuit breaker switch is installed inside the meter and is integrated with the meter. Advantages: simple structure and cheap price. External switch: The miniature circuit breaker is set separately, and the meter can control the opening / closing of the external circuit breaker through the control terminal.
