SMART KWH ENERGY METER Direct connected three phase four wire modular smart energy meter, which is suitable for accurate measurement of commercial and residential electric energy. The energy meter supports LoRaWAN/WIFI/GPRS/4G/NB-IoT/PLC and other hot swappable communication modules to meet the communication function requirements of power users in various countries. The lithium battery required for power off work of the energy meter can also be replaced after installation. Communication module and battery replacement are protected by lead seals.
Features Of SMART KWH ENERGY METER :
- The display screen provides automatic wheel display, key display and other display modes to meet various on site operation requirements of users.
- The energy meter provides various excellent anti-stealing designs, such as current reverse, zero line interference, broken zero line, magnetic field interference, load grounding, unauthorized opening and other abnormal events and real time detection and recording of power theft.
- promote utility asset protection and revenue growth
