DTS726, DSS226 Three-phase Electronic Watt-hour Meter
General
The DTS726,DSS226 series three-phase electronic watt-hour meter is adopted latest micro-electronic technology; used to measure active electric energy of three-phase A.C whole rated frequency is 50/60Hz, coordination meter age of positive and negative. This series meter have to mode of cut-over: cut-over directly and cut-over by mutual inductance electronics
Function and features
2.1 Measure three-phase active electric energy, no need of calibration long-term operation;
2.2 Three phase power supply, lose one (any one wire of three-wire) or two (any two wire of four-wire) phase, uninfected measurement;
2.3 Wide service temperature range;
2.4 Assuming function of defect phase indication or voltage indication.
*Way of display: register, LCD, digital tube.
*Remote interruption of power supply function.
*Output interface RS485.
