Product details
1. Usage description:
The DDS1791 single-phase electronic energy meter is a new product launched by our company. Due to the use of large-scale integrated circuits and SMT manufacturing processes, its measurement accuracy and stability are reliably guaranteed This product meets all technical requirements for single-phase electronic energy meters in GB/T17215-2002 standard Suitable for measuring single-phase AC active energy with a rated frequency of 50Hz and a rated voltage of 220V
2 Functions and Features:
Active energy metering does not require calibration for long-term operation
Adopting specialized large-scale integrated circuits and SMT surface mount technology, the process is advanced and the structure is simple
The electric energy meter has good error linearity within the range of 1% Ib~Imax
All components in the electric meter are made of high-quality electronic components, with long lifespan and high reliability
