Single Phase Two Wires Prepaid Energy Meter RF Card Prepayment Meter Overload Display

DDSY150D electric meter is worked by contact type IC card.However, open IC card, which is easily affected with the environment, need to be protected and will creates extra expense and inconvenience.

Therefore, Radarking designs a kind of prepaid electronic meter with contact-less RF technology, that is, the purchased credit is access into the meter through contact-less IC 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:

• Adopts encrypted contact-less IC card for prepayment, the power company collect the credit by selling the IC card to realize "Pay As You Go".
• Full digitalized metering combing with , power consumption display, prepayment control, card reading and smart anti-tamper, so it has the high reliability.
• Overload protection:the load exceeds about 20%~30% of max. current lasting for 30 seconds, the meter will cut off the power circuit.
• Multiple encryption is used in the card to make sure of safety, accurate, and reliability of the data from the meter, and the card is designed with special technology that can record the remaining credit and accumulated power consumption, and anti-fraud action.
• LCD screen shows the remained credit with two decimals (currency unit: CNY) for 10s, and unit price with two decimals (currency unit: CNY) for 5s, and accumulated/current power consumption with one decimal (unit:kWh) for 5s in scroll.
• Contact-less IC card can adjust to any environment.
• LED lights for power missing.
• One meter can support for multi-user usage in time-sharing period.
• Has the function of time-zone management.
• Supports for maximum demand, and alarm function.
• Magnetic latching relay applied in the meter improves the reliability of the outage power, reduce the power consumption after the outage,also solves the problem of contactor adhesion caused by long time operation of relay under the condition of large current.
• The meter can keep the data once the power outage and get recovered once being powered
