General
The meter is designed to measure single phase two wire AC active energy and variable parameter like residential, utility and industrial application. It has remote read communication port RS485 and WIFI. It is a long life meter with the advantage of high stability, high over load capability, low power loss and small volume.
Basic Function
LCD display, touch button for LCD display step by step
Bi-directional total active energy, reverse active energy measure in the total active energy
The meter also display real voltage, current, active power, reactive power , power factor, frequency, import active energy, export active energy, resettable interval energy
Overvoltage protection, overload protection
Timing and delay control by APP
Prepayment function with APP which meter will cut off when balance is zero
RS485 communication port, MODBUS-RTU protocol
WIFI communication, can read and remote control by mobile phone APP
Pulse LED indicates working of meter, Pulse output with optical coupling isolation
Energy data can store in memory chip more than 15 years after power off
Select outer WIFI antenna (optional function)
35mm din rail installation, bottom type wire connection
