CNDDS309 single-phase electronic energy meter (liquid crystal display)
Scope of application
DDS309-type electronic single-phase energy meter, the use of high-quality large-scale integrated circuits and SMT technology. Stepper motor-driven mechanical institutions of the counter and LCD display counters, power failure is not the loss of recorded data, is the latest structure of one of the energy meter products. This product is used to measure the voltage 220V, reference frequency 50HZ AC single-phase active energy, performance in line with GB / T17215.321-2008 standard.
