Application:
DTS227, DSS227 (Z) the three-phase electronic watt-hour meter is with the LCD or counter display, active energy display together, with A, B, and C three phase voltage, three-phase current, power factor and the time record of break phase, the infrared communication connection and the infrared remote reading switch energy meter, can do the total electric energy measurement for active and reactive: with last month total electric energy for active, last month total electric energy for reactive.
This meter is widely suitable for the electric power measurement terminal and the common user¡¯s electric power measurement instrument, can instead of active, reactive two energy meters, and voltage, current, power factor meter, etc.
