main features

Measure the total positive active energy, total negative active energy, total positive reactive energy, and total negative reactive energy of each circuit separately

Measure the voltage of the busbar

Measure the voltage, current, active power, reactive power, and power factor of each circuit separately

After a power outage, all stored data will not be lost and can be maintained for more than 10 years

● Communication interface: RS485 (not isolated from the power supply line and the secondary side of the current transformer)

Communication protocol: MODBUS-RTU

Communication speed: 1200bps, 2400bps, 4800bps, 9600bps, 19200bps

● Electric energy pulse: Three circuit electric energy pulse output function, taking voltage range of 250V, current range of 1A, voltage ratio of 1, and current ratio of 50 as examples, with a pulse constant of 864/KWh.
