The three-phase cost control intelligent energy meter DTZY3579-Z adopts the latest designed dedicated digital integrated circuit and ultra-low power 16 bit MCU, which can directly and accurately measure the positive and negative active power of the combined phase, the reactive power of the four quadrants, and the positive and negative active power of each phase. It can be set with 4 rates, 14 time zones, 14 daily periods (8 sets), 30 holidays and weekends, etc. It has the function of recording the maximum active power demand, real-time measurement and processing of power consumption parameters such as active power, reactive power, voltage, current, power factor, etc. It has infrared RS485、 Power line carrier communication meter reading (electrical isolation and protection of each communication interface, mutual communication is not interfered with), active and reactive pulse output, load recording and other functions. The data display adopts a large screen Chinese LCD with a wide temperature range, which is convenient for manual meter reading and recording.
●This product is manufactured using SMT technology and advanced equipment, strictly following ISO9001:2000 control process technology and quality;
●Highly integrated design and various anti-interference designs such as anti-static, lightning protection, and transient interference suppression, with key components using internationally renowned brands of low-power, long-life devices;
●Deformation resistance, corrosion resistance, aging resistance, good insulation and sealing performance;
●The performance indicators of this meter comply with the technical requirements for multifunctional energy meters in DL/T 614-2007 and GB/T17215.301-2007 standards, and the communication protocol complies with the DL/T645-2007 protocol and its filing documents;
● It has the functions of measuring positive and negative active energy, four quadrant reactive energy, and apparent energy, and can be used to set the combined active and reactive energy accordingly;
●The demand data can be reset to zero through the meter reset function or the maximum demand reset function;
●The supported demand types include positive active power total and 4-pay rate demand, reverse active power total and 4-pay rate demand, reactive power total and 4-pay rate demand in all four quadrants, combined reactive power 1 total and combined reactive power 2 total and 4-pay rate demand. The demand can be measured according to the set demand cycle and slip time;
● It has two display modes: automatic loop and button; The automatic loop display time interval can be set within 5-20 seconds; When the button is displayed, the LCD starts the backlight, and automatically turns off the backlight after 60 seconds without operation when powered on.
