PEM-3000 can measrue 3 phase 4-wire AC (1) Voltage A, B, C: 110V, 220V and 380V AC, (2) Current A, B, C: 0 ~ 100A, (3) Total Active Power (W), (4) Total Reactive Power (Var), (5) Total Apparant Power (VA), (6) Power Factor (PF), (7) Total Active Energy (kWh) and (8) Total Reactive Energy (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.
