DTSY-669 three-phase electronic energy meter is the active energy metering meter with the data exchange method of numeric medium. The user can load the amount( quantity of electricity) which purchase in advance, make the statement by amount(quantity of electricity). This meter was equipped with numeric keyboard interface used to active energy meteringand prepayment control.Besides, this meter also have infrared communication, RS485, metering components, real-time-clock device, load controlling switch and other auxiliary equipment.This meter can achieve the function of metering, anti-tamper, G3-PLC power carrier remote meter reading, GPRS meter reading, RF (radio frequency) meter reading, LCD etc. Meanwhile having energy testing pulse output function and RTC pulse output.
