  • Product Introduction
  • Technical Data
The meter is used in two phase three wire power grid. The meter is designed to measure AC active energy, mainly export to Peru market. 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.
Basic Function
★mechanical step register 5+1(default) , 6+1, 5+2 , 5 digit no decimal , 6 digit no decimal LCD display 6+1(default) , 5+1, 5+2 , 5 digit no decimal , 6 digit no decimal
★Bi-directional total active energy measurement ,reverse active energy measure in the total active energy
★three phase power supply , the meter also measure when loss one phase (any one wire in three phase three wire ) or when loss two phase (any two in three phase four wire
★loss phase LED indicates working of phase
★reverse LED indicates the reverse current direction or wire reverse connect
★Pulse LED indicates working of meter,Pulse output with optical coupling isolation
★Two type of cases (protective-class I and II) are available
