General Introduction
DDSY energy meters offer many features to public utility and can be classified into two types: DDSY201 Prepaid Single-phase Contact IC Card Energy Meter and DDSY201F Prepaid Single-phase Contactless IC Card Energy Meter.

The main difference of those two energy meters is that DDSY201F adopts RF IC card technology and more advanced than DDSY201, but the technique specifications of the two energy meters are the same.

Characteristics
1. Prepaid, adopts RF (Radio Frequency) and SMT techniques.

2. High accuracy, double display, precise measurement, stability, safe and reliable, low energy consumption.

3. Easy installation and operation.
