Single phase prepaid electricity meter (dual display)

The DDSY825 prepaid electricity meter has multiple anti-theft functions. The DDSY825 prepaid electricity meter has a small starting current, no creep, wide load, and low power consumption. The error curve of the DDSY prepaid electricity meter is straight and stable during long-term operation. The DDSY prepaid electricity meter has a 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
