Din Rail-type Energy Meter
DDZYU2367
Overview
The DDZYU367 Single-Phase Three/Four-Circuit Payment-Control Energy Meter is a patented product innovatively developed by our company. It adopts a DIN35mm guide rail installation structure and LCD, has RS485 communication interface, and is equipped with four-way high-power magnetic latching relays, realizing three/four-way control and three/four-way metering.
This series of electric meters has the advantages of a small size, high accuracy, good reliability, and easy installation. It is suitable for safety management such as electrical control charging, overload tripping, and load identification in college dormitories.
It meets the requirements for branch control of college dormitories, achieves branch metering and branch control for sockets, lighting, air conditioning, and bathrooms, and implements refined management of power consumption.

Functional characteristics
♦ Metering class 1.0, featuring high sensitivity, wide load, and logic anti-creeping logic.
♦ Standard 35mm guide rail installation, large-scale integrated circuit design, small size, convenient installation.
♦ Large LCD, real-time display of important data such as total power consumption, power consumption of branches, and remaining electric quantity of branches.
♦ Have a RS-485 communication interface, and provide photoelectric isolation, effectively preventing destructive interference such as lightning strikes and surges, greatly reducing the maintenance difficulty.
♦ The circuits are equipped with the functions of timed power ON/OFF, automatic power ON/OFF according to the set schedule, overload power OFF, and time-share current limiting.
♦ The circuits can identify the malignant loads and automatically switch off the power supply. The power range of malignant loads and the identification time frame can be set.
♦ The circuits can measure and control the sockets, lighting, air conditioning, and bathrooms separately.
♦ Multifunctional electrical parameter collection, including voltage, current, power, power factor, and electric quantity.
♦ Have the function of recording the reset, timing, remote switch-off, and remote closing.
♦ Parameter localization, capable of independent operation during off-line period, implementing management functions, strict password verification and security certification, and safe and reliable data transmission.
