EM514012 is a three-phase four-wire electronic multi-functional rail meter.
The electricity meter offers options for post-payment and pre-payment modes, supports local communication via RS485 and remote communication via LoRaWAN, and uses the Modbus protocol.
It is equipped with a built-in holding relay. The local relay status can be set through RS485 communication, and the relay can be remotely controlled on/off via LoRaWAN communication, while also enabling remote meter reading. It is widely applicable to both household and commercial power distribution systems.
2.Features
(1) Measurement of bi-directional (forward&reverse) energy, active power, voltage, current, frequency, power factor, and demand quantity etc.
(2) Three Phase LoRaWAN Energy Meter:LoRa Communication LoRaWAN Protocol;Regional Frequency Band: EU868.
(3) Bidirectional Metering:Measurable forward and reverse active and reactive power and energy quantities
(4) Prepaid & Postpaid Model:Supports pre-payment of electric quantity and pre-payment of the electric amount.
(5) Built-in holding Relay: Remote control of electricity meter's on/off state
(6) Overcurrent Cut-off:Set the overcurrent threshold and the overcurrent cut-off recovery time. If the actual current exceeds the threshold, the relay will automatically cut off. After the set recovery time has elapsed, the relay will automatically attempt to close again.
(7) Alarm function:Overcurrent, overvoltage, frequency deviation, low balance/charge level, side cover/top cover detection.
(8) Event Log:Support event recording for recharge, overcurrent, overvoltage, frequency deviation, power outage, low balance/energy level,
