DDSF36 single-phase electronic multi rate energy meter
summary:
The DDSF36 single-phase electronic multi rate energy meter is used to measure 50/60Hz single-phase AC active energy and electricity consumption during peak and off peak periods. All its performance meets the technical requirements of Class 1 single-phase energy meters in GB/T 17215-2002 standard and GB/T 17882-1999 "Special Requirements for Multi rate Energy Meters". The data communication protocol complies with the relevant requirements of DL/645-1997. This product has high accuracy, strong overload capacity, low power consumption, small size, and long lifespan; The data is processed with fault tolerance and error correction to ensure its correctness and reliability; Automatically save all information from the energy meter when power is lost; The LCD automatically displays the total accumulated power, accumulated power for each rate period, real-time power, current date and time, and current rate period markers. Set the functions, clock settings, and time period programming of the table through infrared and RS-485 communication interfaces.

DDSF36 single-phase electronic multi rate energy meter functions:
Total energy metering function: It can measure forward and reverse active energy and accumulate them into total energy, while separately measuring reverse active energy and reverse electricity consumption time
Multi rate time-sharing electricity metering: The electricity meter can be set as a single rate meter, dual rate meter, triple rate meter, or quad rate meter, and measures active energy separately during each rate period.
Rates and time periods: Up to 12 time periods can be set per day, and each time period can be programmed into one of four rates: peak, off peak, off peak, or off peak. The minimum time unit for a time period is 1 minute.
Real time active power measurement
Monthly data transfer function: The electricity meter automatically transfers the total active energy of the month and the active energy of each rate on the set automatic meter reading day and hour. The electricity meter can store up to 12 months of historical data, and the data can be saved for 100 years after a power outage.
Reverse power consumption event recording function: The electricity meter can record the total time of reverse power consumption and the starting time of the last reverse power consumption.
Meter programming event recording function: The meter can record the number of programming times and the time of the most recent programming.
Data communication: Function setting, clock setting, time period programming, meter reading, etc. are performed on the table through infrared and RS-485 communication interfaces.
Equipped with hardware real-time calendar clock
Display/View Function: Using a wide temperature LCD display with Chinese character indicators on a large screen, it displays/views current electricity consumption data, current rates, dates, times, historical data, meter settings parameters, etc.
Applicable conditions:
Working in an environment with a temperature range of -25 ℃ to+65 ℃ and a relative humidity of 85%.
Working voltage range:
