DDZY105 single-phase cost control intelligent energy meter (remote switch)Detailed product description：

Product Introduction:
The DDZY105 single-phase cost control intelligent energy meter (remote/switch) is a new generation of intelligent energy meters developed based on the smart meter series standards of State Grid Corporation of China. Advanced technologies such as ultra large scale digital signal processing chips, permanently stored information memory, fully isolated standard RS485 communication interface and infrared communication, large screen wide temperature LCD display, and information security encryption ESAM module are adopted. The electric energy meter adopts advanced SMT surface mount technology, and the shell is made of high-strength, flame-retardant and environmentally friendly materials, with novel and beautiful shapes, and high insulation strength and corrosion resistance. This meter integrates numerous functions, including electric energy measurement, information storage and processing, real-time monitoring, automatic control, and information exchange, which can effectively prevent overdue behavior and meet the requirements of the power department for modern and scientific management of users in a timely manner.

Main functions:
·Adopting a large screen wide temperature LCD display with backlight illumination, users can view current electricity consumption data, current rate electricity, date/time, historical data, meter setting parameters, etc
·Energy metering function: It has positive and negative active energy metering functions; Time division metering of active electrical energy accumulates and stores total, peak, off peak, flat, and valley electrical energy according to corresponding time periods.
·Remote cost control: The electric energy meter uses RS-485 to pass password verification and security authentication, and receives commands from the remote electricity sales system to open, close, and read ESAM data.
·Multi rate function: equipped with two sets of time zone tables; Two sets of daily time slot tables, programmable with 4 rates and up to 14 time slots.
·A built-in hardware clock circuit with temperature compensation, featuring calendar, timing, and automatic leap year conversion functions, with accuracy superior to State Grid standards.
·It has metering pulse indication, alarm indication, and trip indication.
·Infrared communication and RS485 communication functions: capable of copying all data items supported by the energy meter and setting parameters.
·The case is made of environmentally friendly materials that are insulated, flame-retardant, and UV resistant, and the structural design is sealed and dust-proof.
