5.Manganese copper shunt and NB module:
The current adopts a loop with a highly stable and wide-range manganese copper shunt.
NB module: IoT networking communication, low power consumption. Supports high-efficiency connections for devices with high network connection requirements
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.Card selection and communication method:CPU card / logic encryption card / SD card. RS485, infrared, power line carrier
8.Display information: cumulative electricity consumption in the current month and last month, cumulative electric energy indication value and total accumulated electric energy indication value, current date and time, alarm code or prompt, communication status prompt, meter number of electric energy meter, etc.
9.Metering chip and NB module: A metering chip is used to measure bidirectional active power and four-quadrant reactive energy. The voltage sampling loop adopts resistance voltage division.
10.Optional function- switch built-in
Optional direct access type or transformer access type, optional function- switch built-in
switch built-in: miniature circuit breaker switch is installed inside the meter, and the meter is integrated, advantages: simple structure and cheap price
11.Optional function-switch external
Optional direct access type or transformer access type, optional function- switch external
switch external: miniature circuit breaker is set separately, the electric meter controls the opening / closing of the external circuit breaker through the control terminal
advantages: external circuit breaker ,strong current interruption , not easy to damage.

——Wire Connection Modes——
Fix the electric meter to the meter box, and connect the interface according to the wiring diagram. It is recommended to use copper wire or copper terminal. The screws in the terminal box should be tightened to avoid burning due to poor contact or excessively thin wire.
