At present, the installation of the smart communication electric energy meter generally adopts the traditional wall-mounted installation method, which has the disadvantages of large volume and inconvenient installation. The rail-mounted electric meter adopts the modular design, which has the advantages of small size, easy installation, and easy networking.
Product description
DTSF1352 series electricity meter adopts LCD display, measures electric energy and other electric parameters, can set parameters such as clock and tariff period, and has electric energy pulse output function. The RS485 communication interface can be used to realize data exchange with the host computer.
DTSF1352 series electric energy meters have the advantages of small size, high precision, good reliability, and easy installation. It can be used for sub-measurement of electric energy in government agencies and large public buildings, and can also be used for electric energy management assessment in enterprises and institutions.
Application
Due to its miniaturized structure, DTSF1352 can be conveniently used with miniature circuit breakers and installed in terminal lighting boxes. It provides an effective solution for the energy metering of low-voltage lighting terminals. It can be widely used in buildings, shopping malls, exhibition centers, schools, airports, ports and factories.
Performance characteristics
ACREL has accumulated many years of experience in the design of electric meters, and adopted the international advanced chips and technology to design the DTSF1352 series of rail-mounted electric energy meters. Product design fully considers structural miniaturization, cost efficiency, intelligence and reliability.
Energy metering
Measure forward and reverse active energy, and have power direction indication function
The electric energy is accumulated and stored according to the total, peak, peak, flat and valley respectively
3 months of frozen data stored in the meter
The default setting of the energy data freeze and transfer date is 24:00 at the end of each month (freeze at the end of the month)
After power failure, all stored data will not be lost and can be maintained for more than 10 years
Clock and time slot rates
With hundred-year calendar, time, leap year automatic switching function, the clock error is within 0.5s/day
DDSF1352 can be programmed to set 3 types of tariff rates: peak, flat and valley, and 8 time periods can be set for the daily time period, and the minimum interval between time periods is 1 minute.
DTSF1352 can be programmed to set 4 types of tariff rates: peak, peak, flat and valley, and 8 time periods can be set in the daily time period, and the minimum interval between time periods is 1 minute.
