Product Description

1.General Description
The meter is used in three phase four wire power grid. The meter is designed to measure AC active energy/reactive energy and variable parameter. It can remote read and control from RS485 communication port . It is a long life meter with the advantage of high stability, high over load capability, low power loss and small volume.
2.Basic Function
★LCD display with backlight , keypad for LCD display step by step
★Bi-directional total active energy measurement , reverse active/ energy measure in the total active/reactive energy
★The meter also display real voltage,  current, active power, reactive power , power factor, frequency, import active energy, export active energy, resettable interval energy  
★RS485 communication port , MODBUS-RTU protocol
★Remote control on/off with RS485 communication port
★Pulse LED indicates working of meter,Pulse output with optical coupling isolation
★Loss phase LED indication
★Energy data can store in memory chip more than 15 years after power off
★35mm din rail installation , bottom type wire connection
