General Introduction

Three-phase Contactless IC Card Digital Power Meter adopts advanced RF card and SMT techniques, with double display, accurate measurement, great stability and security, reliable performance, low energy consumption and easy to install.

One meter with one IC card for one consumer, use power only by IC card. When purchased power is used up, it will cut power automatically.  Stop power supply 

Main functions

1. Prepaid: it will automatically cut power when the purchased power is used up.

2. The way of power cut: by controlling switch (inside or outside).

3. Storage function: data in the meter can be kept for 10 years when there is no power.

4. Display: double display, digital wheel records the accumulated quantity of used electric power; LED displayer shows the remaining power quantity and other information.
