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
