Contactless RF Intelligent Electric Meter , Prepaid Energy Meter Using Smart Card

LCD Display Prepaid Metering System with Contactless RF Card Prepaid Energy Meters

DTSY150D three phase electric meter is worked by contactless type RF card which means the purchased credit is access into the meter through contact-less RF card, the unit price of kWh can be set in card, and the meter will deduct the credit based on each 0.01kWh, when the tariff is changed, the management system will reset the card to change the unit price of the meter,so that the meter can deduct the credit with the adjustment of the unit price to reduce the consumption of power company.

1. Main Features:

• Active three-phase electric power metering,no subject to adjust in terms of long working;
• Three phase power supply can assure accurate metering in case of cut off in one line (each line of the three-phase & three-line) or two lines(any two line of the three- phase & four-line);
• Indicative function for phase loss or voltage indication;
• The signal will display after it test;
• Each user(meter) responds to a card, well protect from forgery;
• Once the remanining electric power quality is approaching the alarming power quality, the digital tube should be lighted to remind user of timely purchasing;
• One card just for one meter, fake card is completely avoided.
• Automatic power off when overload, also can prevent the error overload when the load restart
• Two alarm grade to remind purchasing electricity.
• The forward and opposite direction active power can be measured accurately
• Compute the amount of electricity normally in the absence of the phase
• Embedded large power latching bi-stable relay is used to cut off power supply directly.(except 1.5(6) A ), low power consumption, high reliability.
• The electricity is not used for 6 days, energy meter send the power cut off signal.
• It has the functions of failure checkup, anti-stealing electric power and meter record.
• The meter has the high stability and reliability. It is no need to adjust & regulate when long term operation. The data can be saved for a long time if the power is cut off.
• Wide working temperature range, low request to working environment
