category： Energy Meters
reference price：￥$28.94 - $29.67
Application
The meter is used in three phase four wire /three phase three wire /two phase three wire power grid. The meter is designed to measure AC active energy. All of its functions comply with the relative technical requirement for class 1 three phase watt hour meter in IEC62053-21. 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 6+2
2.Bi-directional total active energy measurement ,reverse active energy measure in the total active energy
3.Pulse LED indicates working of meter,Pulse output with optical coupling isolation
4.loss phase LED indication ,Reverse connection LED indication
5.RS485 communication port , MODBUS-RTU protocol
6.Energy data can store in memory chip more than 15 years after power off
7.35mm din rail installation
