Single Phase Pre-Payment Electronic Watt-Hour Meter (DDSY238)

Product Description

Product 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, 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 etc. )backward reading.
3. Storage of leave-factory serial number, meter constants, initial data and the user's name and address etc...
4. Alarm and switch off when overload. Alarm at low remaining power to remind user of timely purchasing.
