Single phase prepaid smart energy meter wifi

Product description

DDSY pre-paid electricity form two-wire state grid meter case liquid crystal display card reader recharge meter using microelectronics technology to measure energy, in line with GB/T17215.321-2008 and GB/T18460.3-2001 standard meter, fully shielded, Fully sealed structure, using advanced SCM processing system for data acquisition, processing and preservation, with good anti-electromagnetic interference, low self-consumption and energy saving, high precision without calibration, anti-electricity, high overload, long life .

Main features: Application of computer management, after the purchase of electricity, after the use of electricity; in the rated current range can limit the maximum use of power; a form of a card, special card, lost card without loss of electricity, make-up card reuse; electric card can be two-way transmission Data; can automatically power off the alarm users purchase electricity; when the electricity is zero, it will automatically switch off and power off; and it has a certain anti-theft software design.

DDSY5188 electronic single-phase prepaid energy meter is suitable for active energy metering with a frequency of 50Hz or 60Hz. It is installed in indoor or outdoor meter boxes for use. Suitable for ambient temperature -20 ~ +50 °C, relative humidity does not exceed 85%, and the surrounding air should not have corrosive gases, to avoid dust, salt spray, condensation and other effects.

Specification

Basic error

Ib is the rated current and Imax is the rated maximum current.

Starting current: The meter has a reference voltage, a reference frequency, and a power factor of 1.0. When the load current is 0.4% Ib/1.0, the meter should have a pulsed output or a flashing light that represents the power output.

Immersion: When the voltage loop adds the reference voltage and there is no current in the current loop, the meter will output no more than 1 pulse within 10 times of a pulse generated by the starting current.

Power consumption: ≤ 2W (10VA)

The main structure: a flame-retardant ABS shell, strong, sealed, and good shielding.

Data processing: The energy metering pulse is sent to the CPU via an optocoupler and stored in the non-volatile EEPROM. From the computer management information system, an IC card reader/writer is used to write a certain amount of power and a microprocessor system that monitors the required IC card input table. After the CPU operation, the display, alarm, and cutoff status signals are prompted.
