It offers a choice for wireless solution, it makes the data reading easier in long distance stand alone meter or in a mesh network.
Multi-functionLoRa communicationPulse output5A CT operatedClass 0.5s/Class 1.0 Accuracy.
Modular (72mm)35mm Din rail mounting LCD display

This meter can be easily used to read KWH in marinas, sublets, or from any appliance or electrical equipment and it can also be used for complex analysis or many other parameters for industrial purposes.

Software available and modular for different size of installations.

This unit measures and displays the characteristics of single phase two wires(1p2w), three phase three wires(3p3w) and three phase four wires(3p4w) networks.
The measuring parameters include voltage(V), frequency(Hz), current(A), power(kW/Kva/Kvar), import, export and total Energy(kWh/kvArh).
The unit can also measure Maximum demand current and power, this is measured over preset periods of up to 60 minutes.

This unit can be setup for 1A, 5A, or 333mV CT operations, it can be configured to work with a wide range of CTs.
Built-in pulse outputs and LoRa module enables wireless communication.
The users are free from Bus line wiring and layout.
Configuration is password protected.

This unit can be powered from a separate auxiliary (AC or DC) supply. Alternatively it can be powered from the monitored supply by linking the voltage reference and neutral reference in to terminals 5 and 6 (Please refer to wiring diagram).

Unit Characteristic:

The Unit can measure and display:
• Voltage (L-N and L-L) of all phases
• Line frequency
• Currents of each phase and Neutral
• Power, maximum power demand and power factor
• Active energy imported and exported
• Reactive energy imported and exported
• THDu % of each phase (total harmonic distortion)
• THDi % of each phase (total harmonic distortion)

Lora wireless communication module combined inside the meter. With Eastron Lora gateway ESP-6, the user can remote monitor and program the meters. It saves lots of labor work for meter reading in sites with many meters, Bus line wiring and maintenance. by LoRaWAN, the communication distance between submeter to gateway can reach several kilometers. by LoRaMesh, data supports 4 relay hopping. The frequency band is 470Mhz. if other band is request, please specify when you order. 433, 869, 915Mhz are available.

Two pulse outputs measured: active and reactive energy.
The Pulse for active energy is 3200imp/kWh. (Terminals 11 & 12)
The pulse width for Pulse 1 can be set from the set-up menu (Terminals 9 & 10).
