DTS634 Three-phase Electronic Watt-hour Meter
DTS634、DSS633 three-phase electronic watt-hour meter(hereinafter called electronic meter) , use for the measurement of forward and reverse three phase active electronic meter, the internal use of imported digital multiplier measurement chip, has high measuring accuracy, simple peripheral circuit, anti-interference capability and Characteristics. In accordance with IEC62056-21 standard.
Main functions and features:
◆ It can measure three phase forward、reverse active energy, the forward measurement of reverse electrical energy
◆ All products adopt stable performance、low power consumption of industrial components, use the SMT craftsmanship carefully design and manufacture.
◆ Phase failure indicator function (optional):When A, B, C three-phase have electricity, yellow, green, red lights are bright ( or out ), when one or two phase is powered off, then the corresponding fault phase indicating lights will be extinguished ( or light ), indicating the phase power off, which corresponds to A yellow indicator lamp phase, green indicator corresponding to B phase, the red indicator light is corresponding to C phase.
