Three phase four wire electronic multi rate energy meter (LCD)

Product Details

product overview

The DTSF121 series three-phase four wire electronic multi rate energy meter consists of an electronic three-phase energy metering unit and a multi rate processing unit. High reliability, intuitive display, with infrared communication and 485 communication functions. This meter has significant advantages such as high measurement accuracy, good stability, and strong overload capacity, and can provide advanced and reliable measuring tools for three-phase time-sharing billing. This phenotype complies with the national standards DL/T614-1997 "Multifunctional Meter Communication Protocol" and GB/T17215-2002 "Level 1 and Level 2 Static AC Active Energy Meters".

Performance characteristics

1. The three-phase four wire electronic multi rate energy meter (LCD) expands the four basic rates of peak, off peak, flat, and valley to eight rates. The meter has eight rates of peak, off peak, flat, valley, and digital combinations, which can be used to measure energy and demand according to the peak and valley periods of electricity consumption, and store current, previous, and previous month data.

2. The meter can be flexibly set up to twelve rate periods within twelve time periods, with a minimum interval of 30 minutes between periods and a switching error of less than 1 second

3. The three-phase four wire electronic multi rate energy meter (LCD) displays data such as electricity quantity, date, meter number, and current time period, making the display intuitive.

4. The programming meter reading adopts the infrared simple programmer produced by our company to record and set all data of the energy meter (meter number, electricity quantity, demand, clock, etc.).

5. High reliability, good battery compatibility, minimal power consumption of backup batteries, and a lifespan of up to 7 years.

6. Three phase four wire electronic multi rate energy meter (LCD) displays energy to one decimal place, with optional meter reading days and display digits.

7. Infrared handheld computers can be used to record the electricity level, demand, occurrence, time, clock, time period, and battery level of the energy meter.

8. Three phase four wire electronic multi rate energy meter (LCD) with photoelectric output interface, pulse output width of 80ms ± 20ms

9. The three-phase four wire electronic multi rate energy meter (LCD) has RS485 output and uses lightning resistant 485 chip.

10. The three-phase four wire electronic multi rate energy meter (LCD) can support the DL/T645-1997 protocol of the Ministry of Electric Power and multiple provincial power company protocols.
