Application:

DTSY1666 series three phase static watt-hour meter adopt large-scale integrate circuit, 16-digit A/D changeover, digital multiplier and SMT technology. It is able to measure three-phase positive and negative active energy.

Structure:

l       Independent three-unit measuring module

l       Prevent thieving actions caused by wrong phase sequence, current reversing, difference phase between voltage and current, voltage breaking or zero wire breaking

l       Anti-interference of electromagnet

l       Low self-consumption

l       High accuracy
