Single Phase Electronic Prepayment Power Watt-Hour Meter DDSY**0

Three-phase electronic prepayment meter used the entire digitized electronic meter special-purpose chip group. Take integrated circuit card（IC card）as to pay the bill with the control medium complete digitized intelligence electronic metering device. It’s a new generation of products, it has the complete digitized electrical energy measurement, the intellectualized charge control and the user information management the multi-purpose functions and so on. And it is an ideal product on the current situation of reforming electric power consuming system, commercializing electric power, solving the problem of the collection of charges, as well as adjusting load state of electrical network. Features: ＊ Product’s Type: One Card One Meter, Multi Cards One Meter, One Card Multi Meters, Special Load Identification; ＊ Electric Power Measurement: Positive active power and reverse active power which can be measured; ＊ Prepayment: IC Card prepaid, electricity sector receive energy charge in advance through selling IC Card. User pay first; ＊ Ladder Billing: Two schemes for electricity price. It can automatic changeover when at promissory time or reach certain value; ＊ Manner of Working: Warning/Overdraw Manner. Warming/Overdraw electricity, maximum accumulations can be set; ＊ Protections: Over Voltage, Over Current, Over Load Protections; ＊ Display Method: LED or LCD display the rest electricity(charge), cumulative electricity consumption, current power in alternant way; ＊ Reliable Design: Perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation; ＊ Cover for Meter: Fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties; ＊ Interface Protection: Perfect interface protection circuit, which keeps the meter from all kinds of vicious attack, no damaging for meter, no lose for data, and no delay for active; ＊ Communication Mode: Infrared, RS**5 interface or carrier communication module (Optional); ＊ Power Supply System: Three-phase power supply or it can work while just one phase has electricity if three phase four wires; ＊ Management System: Suit for Digital IC Card Smart Electric Meter Management System(SKZHSFN3.**-SD), Water/Electricity “One Card” Management System (SKZHSFN3.**-YKT).
