DTS222 Three phase four wire electronic active energy meterDetailed product description：

The DTS222 fully electronic three-phase active energy meter is designed and manufactured using ultra-low power large-scale integrated circuits and SMT technology. It is equipped with a high reliability mechanical meter to accumulate and indicate electrical energy, and is used to measure AC active energy in a rated frequency of 50HZ three-phase power grid. Complies with all technical requirements of Class 1.0 three-phase energy meters in IEC1036 and GB-T17215.

The main functional features of DTS222 three-phase four wire electronic active energy meter are:

1. High precision, high reliability, wide load capacity, low power consumption, small size, light weight, and good structural performance.  
2. Has three-phase voltage loss indication for A, B, and C.  
3. When one phase of a three-phase three wire network and two phases of a three-phase four wire network experience a power outage, the energy meter can still measure normally.  
4. Equipped with a photoelectric coupling pulse interface.
