【General Introduction】
Adopting with special large-scale integrated circuit and manufactured with advanced SMT process , DT(S)S22(B) Three Phase Four(Three) Wire Active(reactive) Electronic Meter is featured whit high degree of measuring accuracy, reliable and stable performance, long service life and low power dissipation. And it is used to measure parameter frequency 50Hz three phase active energy.

 

【Functions and Characteristics】 
* To record active energy cumulatively no matter direct or reverse.
* Tamper proof. The meter record energy normally when one or two phases reversal.
* RS-485 communication port(optional).
* Large LCD display 
* The mechanical register can display the active and reactive power consumption and prevent tempering with influence of external AC/DC magnetic.
