IC card smart meter (single-phase ordinary type)

DDSY prepaid electricity meters have various anti-theft functions. DDSY prepaid electricity meters have low starting current, no creep, wide load, low power consumption, straight error curve, and good stability during long-term operation. DDSY prepaid electricity meters have beautiful appearance, small size, light weight, and easy installation.
DDSY prepaid electricity meter has high accuracy: fully electronic design, built-in imported dedicated chip, accuracy is not affected by frequency, temperature, voltage, and high-order harmonics.
Long lifespan: Adopting SMT technology and optimized circuit design, the whole machine does not need to adjust the circuit after leaving the factory.
Low power consumption: Adopting a low-power design to reduce power grid line losses.
Pre order electricity quantity; Non contact IC card transmission of data, realizing data reading back, including: reading back total power consumption, remaining power consumption, accumulated purchased power consumption in the meter, total purchased power times, and other information.
Store table constants, initial values, user addresses, names, and other information.
Overload alarm, power outage, remaining battery alarm, reminding users to purchase electricity in a timely manner.
Technical parameters: Adopting a long-life base table to extend the service life
