DDSY150 Prepaid Domestic Electric Meter , IC Card Single Phase Energy Meter

Domestic Prepaid Metering System with Single Phase Two Wire IC Card Prepaid Energy Meter

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.

1. Main Features:

• Perfect Interface Protection: the meter has the capability to protect circuit against malicious attacks.
• Scrolling Display: the show time of different metering parameters is 10s for residual electricity fee (Two decimals, CNY), 5s for unit price, 5s for accumulated power consumption (One decimal, kWh) and 5s for the current power consumption (One decimal, kWh)
• Easy-To-Read: The total and unit price of electricity inside the meter is accumulated in the unit of four decimals and CNY.
• Has the feature of partition management.
• Supports for max. hoarding electricity quantity and alarm mode.
• Magnetic Latching Relay Applied: it can improve the performance of outage movement and lower the power consumption after power failure, and meanwhile, also can get rid of the contactor adhesions when the relay is being worked under the large current for a long time.
• The meter will keep data or get recovery when being powered on./off automatically.
• Pay As You Go: IC card that adopts " Financial Card Project" hardware encryption technology is used by the Power Company to collect the electricity fee in advance.
• Metering active electric energy, without the need of tuning for long-term work;
• One meter (household) one card, multiple encryption, with good anti-counterfeiting;
• When the remaining electric quantity is equal to the alarm quantity, the indicator lights to remind users of timely purchase;
• Trip and power off when the remaining electric quantity is 0;
• Prevent electricity larceny and record illegal electricity consumption information automatically;
• Overload automatic power-off facilitates the power sector to implement capacity increase;
• Large-capacity magnetic latching relay, with low power consumption and high reliability;
• With data write-back function, it is easy for the management of power sector;
• As long life and high reliability electronic components are selected for all the components inside the meter, the meter has;
• Characteristics of long life and high reliability;
• The supporting IC card electricity sale management system has the functions of complete electricity sale management, electricity consumption monitoring, etc.;
