Description
RS485 single phase 2 wire of electric energy meter DDS238-1 ZN
Application
Application
The meter is designed to measure single phase two wire AC active energy like residential , utility and industrial application. It has remote read communication port RS485 . It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume .
Product features
Basic Function
- LCD display with backlight
- Bi-directional total active energy ,reverse active energy measure in the total active energy
- The meter also display real voltage , real current , real power , real power factor , real frequency ,import active energy , export active energy
- keypad for LCD display step by step
- reset energy function (the reset energy kWh display is dependent with the total energy display, this reset will not affect the total energy )
- RS485 communication port , MODBUS-RTU protocol
- 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
- 35mm din rail installation
Optional Function
- Other function also can be special design as customer requirement
other voltage , current are also available
