Description:General: The model DDSY238 single phase prepaid electronic meter, briefly named as single-phase intelligent card watt-hour meter, is used for measuring single-phase AC active energy with rated frequency of 50Hz to realize using electric power after prepayment. The product adopts IC card (named as smart card) and advanced micro-electronic technique to collect, process and memorize data. Its technical performances are complying with the requirements of national standards of GB/T18460.3 and IEC61036. It has strong function of preventing the meter from decoding, compatibility as well as features of small size, weight light and high reliability. Working principle: 1. Both-way electric energy metering: provides precise positive-negative active energy metering and one-way accumulating; used for power metering and advance purchase of AC single-phase current rated 2. Advance purchase quantity, preset maximum load-limit and IC card password; IC card transfers data and realizes data including total consumption, remaining quantity, accumulated quantity and total purchases) backward reading 3. Storage of leave-factory serial number, meter constants, initial data and the user's name and address 4. Alarm and switch off when overload; alarm at low remaining power to remind user of timely purchasing Technical data: Applicable standard: IEC61036 Service lifetime: 10 years Accuracy class: class 1, class 2 Working voltage range: 0.9~1.15Un Power: loss less than 2W or 10VA Specifications: Rated voltage: 220V, 230V Reference frequency: 50Hz Class: class 1, class 2 Basic current (maximum current) A 1.5(6), 5(20), 10(40), 20(80) 2.5(10), 5(30), 15(60), 30(100) Or other specified meters Outer dimension: 164 x 110 x 62mm
