DTSF/DSSF series electronic three-phase multi rate energy meter

product details

Product Introduction

Composed of an electronic three-phase energy meter unit and a rate unit, with LCD display and infrared or RS485 communication function. This meter has significant advantages such as high measurement accuracy, good stability, strong overload capacity, and high reliability. It can provide advanced and reliable measuring tools for three-phase time-sharing billing. This phenotype complies with the national standards GB/T15284-2002IX Multiple Rate (Time of use) Energy Meter and GB/T17215.312-2008 Static AC Active Energy Meter for Level 1 and Level 2, and the communication protocol complies with DL645-2007 Multifunctional Communication Protocol. The product meets the technical requirements and communication protocol of electronic three-phase multi rate meters.

Function and characteristic

Four rates (peak, off peak, flat, valley), twelve stages, with a minimum time interval of 5 minutes between each period;

● Store energy data for each rate, including the current month, for the past 12 months;

Automatic recognition of power (electrical energy) direction, automatic storage and accumulation of reverse power in the forward power counter, automatic recording of reverse power, reverse start time, and total reverse operation time;

● Equipped with reverse pulse detection and indication function

● Electrical isolation RS485 interface, and designed with lightning protection circuit:

When writing data, two levels of protection are used: password and programming switch, automatically recording the last programming time and number of times:

● Adopting hardware clock circuit with extremely low current consumption, the backup battery adopts imported green and environmentally friendly disposable lithium battery: ● It can set meter number, bureau number, time period, rate, date, time, automatic meter reading, password, cycle display item and starting power;

● Equipped with backup battery undervoltage detection indication, meter hardware status, meter communication status, clock status, power direction, timing status, and current time period status, and other meter operation status identification bits, which can be read through RS485 or handheld computer;

During power outages, the electricity meter can switch months on the day of automatic meter reading.
