LCD Display Prepaid Energy Meter Single Phase Two Wires IC Card Energy Meter Pulse Output
1. Introduction:
DDSY series electronic type single-phase prepaid meters are new IC card type prepaid electric energy meters with multiple functions of electric energy and load control and user location management, etc., researched and developed based on our company's electronic type single-phase electric energy meter of excellent performance. The meter is an ideal product under the current reform of electricity system to achieve electric energy commercialization, solve the difficulty in charging and adjust the grid load state. All performance indicators of this product conform to GB/T17215 321-2008 Electricity Metering Equipment(a.c.) -Particular Requirements-Part 21:Static Meters for Active Energy (classes 1 and 2) and all the technical requirements for electronic type single-phase prepaid electric energy meters in GB/T18460-2001 and IECl036-2002 technical standards.

3. Main Features:
Metering active electric energy, without the need of tuning for long-term work;
4. Display and Appreance:
Features
1. Product's Type-- One Card One Meter, Multi Cards One Meter, One
Card Multi Meters, Special Load Identification.
2. Electric Power Measurement-- Positive active power and reverse active power which can be measured.
3. Prepayment-- IC Card prepaid, electricity sector receive energy
charge in advance through selling IC Card. User pay first.
4. Ladder Billing-- Two schemes for electricity price. It can
automatic changeover when at promissory time or reach certain
value.
5. Manner of Working-- Warning/Overdraw Manner. Warming/Overdraw
electricity, maximum accumulations can be set.
6. Protections-- Over Voltage, Over Current, Over Load Protections.
7. Display Method-- LED or LCD display the rest
electricity(charge), cumulative electricity consumption, current
power in alternant way.
8. Reliable Design-- Perfect power source and electromagnetism
compatible design, which are suitable to the strong
electromagnetism disturbance and big occasion of power source
fluctuation.
