               DDSFY single-phase electronic multi-charge prepaid power meter

The DDSFY single-phase multi-fee-rate prepayment power meter is a new type power meter which integrates the functions of the single-phase multi-fee-rate power meter and the single-phase prepayment power meter. This meter has the prominent advantages of high measurement precision, good stability, strong overload capacity, high reliability, etc. It can provide the single-phase time-share prepayment power supplies with advanced and reliable metering tools, and is an ideal product for reforming the current power-usage system, achieving power commercialization and solving the difficulties in charging.

 Functions and characteristics:

  1. Adopt the big-screen wide-temperature LCD with the backlight to display the electricity volume and parameters at the same time, and the display is intuitionistic and clear, convenient for meter recording.

  2. Prepaid electricity use with IC card, one card for one household, with the good anti-counterfeiting performance

  3. Two types of measurement means of electricity volume or amount

  4. Two-level alarm mode. When the residual electricity volume is smaller than Alarm 1, one alarm will be sent for 0.01 degree of electricity used, and when smaller than Alarm 2, the power will shut down, to send the serious alarm, reminding the customer to buy the electricity promptly.

  5. Load control: When the customer exceeds the load for three minutes, the meter will shut down, reminding the customer to reduce the electrical load, and it will be recovered after 5 minutes or by inserting the card.

  6. Measurement of electricity volume in positive and reverse directions, and four types of rates in tip, peak, plane and valley, and the data in the current month and the past 12 months will be saved.

  7. Daily time periods: 12 rate periods at maximum, to measure the electricity volume at peak, plane and valley for different rate periods

  8. Programmed meter recording: Adopt the handset microcomputer for meter recording from Zhenzhong Company or other computers for meter recording, to input the meter No., and through infrared or RS485 to set up the meter and record all the data on the meter (Bureau No., total electricity volume, residual electricity volume, electricity volume at rate, current time, rate, status, and period, etc.)

  9.Width of pulse output is 80ms ± 20ms, which can be used for calibrating the meter or collecting the pulse, and the second pulse output from the clock can be used for testing the clock  precision (23°C  1°C)

  10. RS485 and infrared interfaces can be expanded.
