1.1 Description
DDZY1737C-DC is a direct current smart energy meter designed with advanced energy metering chip and SMT technology. With RS485 port, the meter can communicate with the computer to exchange the data.
1.2 Main Function
  • Current combined energy consumption and current monthly consumption can be separately measured
  • Measure current, voltage, consumption and power
  • Record and alarm of under-voltage, over-voltage, power-failure, etc.
  • Automatic reading monthly with latest 24 months 'data stored
  • The data of current, power, consumption, time (year, month, day, hour, minute, second) will be stored once a minute and 1500 records can be stored for each item.
  • Store monthly frozen energy with storage capability of 24 records
  • Record and store the latest 500 alarm records
  • Local storage function to avoid energy data loss
