Baud Rate: 19200
Parity Stop Bits: 1
Data Bits: 8

Measurements on the LoRa electricity meter

- Active power (kW)

- Reactive power (kvar)

- Apparent power (kVA)

- Current (A)

- Consumption of active energy (kWh) and delivery (kWh)

- Reactive energy consumption (kvarh) and delivery (kvarh)

- Frequency (Hz)

- Number of power interruptions

S0 pulse output

In addition to the LoRa radio interface, the EMU Professional II energy meter has a configurable S0 pulse output.

- Active energy consumption or active energy supply

- Reactive energy consumption or reactive energy supply

Factory configuration with direct connection: 1,000 pulses/ kWh, 40 ms

Rate Control

 Rate switching occurs by connecting 230VAC to the corresponding terminal.

0 = no voltage; 1 = 230VAC,
