Single-phase multi-function electronic energy meter
1. Flame retardant,small size,easy to install
2. The energy meter has the function of multiply tariff(variable rate)
3.Communication method: RS485, infrared
4. With event recording function
5. There are two sets of rate schedules, which can be automatically converted at the agreed time
6. Can measure voltage, current, power, power factor and other parameters
1.Display with LCD display with wide viewing angle and high contrast
2.Voltage sampling loop adopts resistance voltage division
3.Apply digital processing technology and SMT process
4.High-precision, high-sensitivity, high-stability, wide-range, low-power dedicated metering chip
5.Manganese copper shunt:The current adopts a loop with a highly stable and wide-range manganese copper shunt.
6.Applicable place:community,hotel,shopping mall ,office building,school,property,etc
7.Communication method: RS485, infrared
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.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
10.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.
Software: add special encryption algorithm; open the alarm record.
Hardware: Add the top cover and the tamper-evident seal of the tail cover.

——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.
