The meter is designed to measure single phase two wire AC active energy and variable parameter. All of its functions comply with the relative technical requirement for class 1
single phase watt hour meter in IEC62053-21 and its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. It is a long life meter with the advantage of high
stability, high over load capability, low power loss and small volume.
Basic Function
1.LCD display
2.Bi-directional total active energy measurement,reverse active energy measure in the total active energy
3.The meter also display real voltage, real current, real power, real power factor, real frequency, real time and date
4.Pulse LED indicates working of meter,Pulse output with optical coupling isolation
5.35mm din rail installation
Optional Function
1.LCD with backlight, can see in dark
2.Remote control function , the meter has function of remote control on/off through RS-485(DDS238-4 ZN/SR type)
3.the meter can measure and display the total forward/reverse active energy
4.reset energy function (the reset energy kWh display is dependent with the total energy display, this reset will not affect the total energy)
