智慧三相電能監測器 - PEM-3000
WiFi
LoRa
特性
PEM-3000 可測量三相四線交流 (1) 電壓 A、B、C：110V、220V 和 380V AC，(2) 電流 A、B、C：0 ~ 100A，(3) 總有功功率 (W) , (4) 總無功功率(Var), (5) 總視在功率(VA), (6) 功率因數(PF), (7) 總有功電能(kWh) 和(8) 總無功電能(kVarh)
PEM-3000 can transmit the measured values using (1) MQTT/WiFi, (2) WiFi and (3) LoRa techniques. Methods (2) requires MQTT server and method (3) requires LoRa Gateway to relay the received messages to the MQTT Server. Messages processed in the MQTT Server can be displayed in the remote PC monitor.
