3 Phase 4 Wires LoRaWAN Energy Meter Electric Kwh Meter With LCD Display
Introduction:
DTS150 series FBR(LoRaWAN) three phase four wire electric energy
meter adopts advanced SMT production design and manufacture.
Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc.
It sends data to corresponding gateway through LoRaWAN wireless network.
It has advantages in high accuracy, low power consumption, and good
stability that can be widely used for the single phase alternating
current in city, rural areas or factory enterprises, etc.
Product overview:
Measurement: threephase voltage, threephase current, active power,
reactive power, power factor, frequency, active energy, reactive
energy.
