DTSY150D IC Card Three Phase Prepaid Meters , LED Display Active Energy Meter

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

• 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.
