The DDS1531 single-phase electronic energy meter uses microelectronics technology to measure electrical energy. The product complies with the standards of GB/T17215-2002 "Level 1 and Level 2 Static AC Active Energy Meter" and GB/T18460.3-2001 "Prepaid Energy Meter". The meter uses an advanced microcontroller processing system for data acquisition, processing, and storage, and has strong anti electromagnetic interference ability, low power consumption, anti electricity theft, and long service life. Its outstanding feature is to pay before using electricity, completely solving the problem of electricity bill arrears. The sales management software is designed rigorously and easy to use, so it is highly favored by electricity management departments.

Active energy metering, long-term operation without calibration, using dedicated large-scale integrated circuits and SMT surfaces [easy installation, advanced technology, simple structure], using manganese copper shunt as circuit reflux, greatly improving the overload capacity of the instrument, making the actual overload capacity more than 6 times, and making the meter a strong anti-theft power meter with a wide working temperature range: -30 ℃ -55 ℃
