General Introduction
Smart Card Single Phase Digital Energy Meter offers many features to public utilities and has two types: Contact IC Card & Contactless IC Card energy meter.
The main difference of those two energy meters is that Contactless IC card energy meter is more advanced, water proof, dust proof and anti-attack.
Standards
GB/T17215.321-2008 Grade A and Grade B Static AC Active Energy Meter
GB/T18460-2001 Prepaid Energy Meter
Characteristics
1. Double display by mechanical wheel and LED, more accurate and avoid dispute between Power Company and clients.
2. Adopted chips from American Microchip and ATMEL Corporation, which can guarantee the quality of product. More safe, reliable and offer/secure solid operation.
3. One IC card registers one meter, no interchangeability.
4. Wireless transmission between meter and IC card, easy to use, more quick and convenient.
5. In case of reverse connection, meter still records the used electricity to prevent illegal use.
