IC Card Prepaid Energy Meter Single Phase LCD Power Meter with Power Display
1. General:
Traditional prepaid electric meter is normally working by the means of Multi-Card One Meter, electricity consumption measurement or No Card to deduct the purchased electricity (unit: kWh ) after being inserted into IC Card. However, the price fluctuation of electricity market which cannot reflect in the purchased electricity will increase the losses of Power Company.
For this purpose, a new designed prepaid electric meter Model No. DDSY150 D/F/A issued by Radarking adopts the electricity fee ( Unit: CNY) way, that is, when the fee is transmitted into through Client IC Card and the meter will deduct the price of electricity ( 0.1kWh as base ) according to the unit price, which is set on the IC Card to be transferred into the meter. When the electricity rate changes, the unit price of electricity in the meter will also be changed through the communication medium IC card that the modified unit price are written into from the vending system.
2. Function and Features:
2.1 Active three-phase electric power metering, no subject to adjust in terms of long working;
2.2 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);
2.3 Indicative function for phase loss or voltage indication;
2.4 The signal will display after it test;
2.5 Each user(meter) responds to a card, well protect from forgery;
2.6 Once the remanining electric power quality is approaching the alarming power quality, the digital tube should be lighted to remind user of timely purchasing;
