Wireless IC Card on Prepayment Meter

We are the Leader on wireless IC card technology on smart meters.

This is a special smart meter, No need IC card.

It is wireless, base on Infr Technology support Prepayment meter.

There are more than 600000 meters in China form 2005year.

Single-phase and three-phase Electronic Prepayment Energy Meter is used to measure active power at the rated frequency 50Hz. Meanwhile it fulfills the prepayment function of buying before using power and the load control function.

Prepayment power using mode, paying for the power before using it. (Can also set to pay after use based on the actual condition)

Pre-alarming for Balance Value or Credit Deficiency

The power utilities can set diverse alarming threshold and mode to suit different type of users: High threshold for high consumption users and lower thresholds for users consumes less. Thus to make various types of user under different condition to purchase power in due.

Overload Control

1). Delayed disconnection of power when overload occurs, while records the overload quantity indepently; Time of delayed disconnection is programmable.

2). only records overload quantity without disconnection

Overdraft Power Use (Optional)

Communication (Optional)

Builds with RS-485 or Infrared communication. To read meter data and control the relay via the communication port.

Reversal consumption meausres as positive

Double circuits design to prevent fraud by reversal use, meanwhile accumulates fraud time and indicates fraud on LCD display.

External alarming device compatible

When balance power or value reaches theshold, the externl connected alarming device will give out signals to remind the user to repurchase power or lower down the power load. Auto save of meter data when power failure; Preserves data for over 10 years. To read, replace and configure the meter by using the card with special functions.

Multi-application card to utilize in prepayment water meter, gas meter and other utility payment system
