Single Phas Contactless Card Static Prepayment Watt-hour Meter

The model DDSY150 single phase prepaid electronic 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.
