DSS3/DTS3 Three-Phase Static Active Energy Meter Electric Energy Meter

Summary of DSS3/DTS3 Three-Phase Static Active Energy Meter Electric Energy Meter :
DSS3/DTS3 three-phase static energy meter is based on special large scale integrated circuit and SMT technology; by adopting microelectronic and computer technology as core technology and depending on modern management. We developed this metering product with high dependability and precision. It' s one of the newest energy metering products in the world. It meets all technical requirements of IEC 62053-21: class 1 and class 2 static alternating active watt-hour meter, it measures positive and negative active power energy with frequency of 50/60Hz in three-phase electricity network.

Structure of DSS3/DTS3 Three-Phase Static Active Energy Meter Electric Energy Meter :

Product Function of DSS3/DTS3 Three-Phase Static Active Energy Meter:
1. Bi-directional measure function, precisely measure positive and negative power, free from checkout in longtime, accumulate
electricity energy in one direction.
2. Three-phase power supply, the metering accuracy is out of influence when one or two phase break down, phase shortage
state is indicated as light is off. 
3. Adopting the photoelectric isolation technology to output impulse signal, LED power indication.
