Product Description

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.

Electrical parameters

Basic current Ib	5(30) A, 10(40) A, 20(80) A
Accuracy level	2.0 class
Reference frequency	50 Hz

Essential function

Prepayment function:
Meter inputs vending amount by touch CPU user card, at the same time, power price, alarm amount, maximum hoarding amount, draft limit amount and capacity parameter can be changed. And these can also be changed by RS485 communication, IR communication.
 

Power price management function:
Power price settlement requires coexistence of tariff power price and step power price.
Power price can be changed, but must adopts cipher-text data.
