Overview:

DTSF637. DSSF637 three-phase electronic multi-rate active energy meter is produced by our factory according to GB/T17215. 321-2008 "Class 1 and Class 2 Static AC Active Energy Meter", DL/T614-2007 "Multifunctional Energy Meter" , GB/T15284-2002 "Multi-rate electric energy meter, special requirements" and other standards for design and manufacture. This product adopts high-performance microprocessor chip, ferroelectric memory, hard clock and temperature compensation circuit, and the output frequency of the internal clock terminal is 1Hz. The communication protocol conforms to the requirements of DL/T645-2007 "Multifunctional Electric Energy Meter Communication Protocol".

Main features:

With time-of-use active metering function, record and display current and previous month data.

It has the function of reverse detection and indication, and the reverse power is automatically accumulated to the forward power.

The automatic meter reading day can be set to any day of the month, and the default is 0:00 on the 1st; the meter can store historical electricity data for 12 months.

3 types of rates and 12 time periods can be set; the minimum interval between time periods is 1 minute.

6-digit Chinese LCD liquid crystal display, the default display is 5-digit integer, 1-digit decimal: and can be set. Display items and display time can be freely set (up to 1 to 4 items). With real-time rate indication function.

Programming with hardware protection and secondary password protection

With RS485 and infrared communication interfaces, the communication does not interfere with each other, and realizes remote meter reading and wireless meter reading.

Using a hardware clock circuit, the daily timing error is less than 0.5s/d (23°C); the change with temperature is better than 0.1s/(d.C).

The long-life, high-performance green battery is used as a backup power supply to maintain the clock for more than 3 years; the data will never be lost after a power failure, and it will be stored for more than 10 years.

It has the function of broadcasting school time.

With clock and power pulse test output port.

Scope of use:

220V1.5 (6) A-30 (100) A, this meter is especially suitable for electric energy metering and control of urban and rural residential users who have time-of-use billing requirements.
