Product Description

DTSYF668 electronic single-phase card prepaid meter is designed with advanced special integrated circuits and manufactured with fully automatic surface mount (SMT) production technology. The circuit design and component selection of the meter are based on a large environmental tolerance, which can ensure long-term stable operation of the whole machine, high precision, high overload, low power consumption, and high reliability. It adopts advanced smart IC card technology that meets international standards to realize prepayment mode, and has a built-in magnetic latching relay. The load is controlled on and off by controlling the relay, realizing the function of urging users to buy electricity before using it.

Essential function

Energy measurement, payment counting function:
It should be able to measure active total power,  sharp, peak, flat and valley power quantity, and store data. It has forward reverse active power measuring function, and reverse and active power accumulates by forward energy.
 

Tariff time interval function:
When changing time interval, meter will automatically store data of freeze time interval in time interval change freeze data, and only the latest 5 freeze data of time interval change will be stored.
 

Freeze settlement function:
Automatic freeze when changing power price and time interval, and freeze data will be stored in power price change freeze data or time interval change freeze data.
 

Prepayment function:
When user card inputs purchase amount into the meter, the balance in the meter will automatically accumulates the purchase amount (automatic decrease will be run when balance is negative value).
