Summary

DTSD193/DSSD193 type three-phase multi-function watt hour meter, (hereinafter referred to as the instrument) is my company in order to adapt to China's power grid transformation, to adapt to China's national conditions and the development of active power meter. It has high accuracy and feasibility. The instrument adopts the international advanced ultra low power consumption large scale integrated circuit technology and SMT advanced technology, the key components of international brands, long-life devices, improve product reliability, prolong the service life. The meter is used to measure the active and reactive power, and the power can be copied by infrared communication. This instrument is designed to meet the standard GB/T 17215.321-2008 "1 stage and 2 stage static AC power meter," GB/T 17882-1999 "2 level and 3 level AC static reactive power meter," DL/T 645-2007 "multi function watt hour meter communication protocol" on the three-phase electric energy meter related technical requirements.

Main features

■The measurement of active power, total reactive power and reactive power with time sharing

■With 12 months of active and reactive power record function

■The maximum amount of reactive power and reactive power demand and the demand of the time, the demand cycle is 15 minutes, slip time is 1 minutes

■Three phase power supply, one phase or two phase power, measurement accuracy is not affected. After power off, all stored data is not lost and can be maintained for more than 10 years

■When the battery voltage is low, the alarm indicator light is on, and the corresponding battery symbol on the LCD is used to indicate the flicker

■It can carry on the infrared communication through the handset terminal or the PC machine, completes the programming and the meter reading. Communication symbol bright, convenient and intuitive and reliable

■Wide temperature and large liquid crystal display all kinds of information; electric energy display bit 6 bit integer, the 2 decimal

■The electric energy meter has two kinds of communication modes, infrared and RS485, and the communication protocol accords with the DL/T645-1997 communication protocol of Multi-function Energy Meter

■Energy meter using 3.6V, 1.2Ah high capacity lithium battery, the normal life of 10 years

■It has the functions of time freezing, instantaneous freezing, convention freezing, daily freezing and freezing

■The programmable switch open, the correct password state, by a "handheld meter zero" command, can remove all of the electricity and electricity events

■The external clock chip has the functions of calendar, timing and automatic switching
