DTS726 Three-phase Electronic Meter

General

The meter is used in three phase four 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.

Function

1. Mechanical step register 5+1(default) , 6 digit no decimal OR LCD display 6+1, 5+2;
2. Bi-directional total active energy measurement ,reverse active energy measure in the total active energy;
3. 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;
4. Loss phase LED indicates working of phase;
5. Pulse LED indicates working of meter, Pulse output with optical coupling isolation; 6. Two type of cases (protective-class I and II) are available.
7. Internal connection between the voltage circuit hook and current circuit hook in order to anti-tamer.
