Overview

The rail-mounted multi-circuit fee-control smart electric meter adopts a DIN 35mm rail-mounted installation structure and LCD display. It features an RS485 communication interface for data exchange with the host computer and has three built-in high-power magnetic latching relays to achieve triple control and triple metering.

This series of electric meters has the advantages of compact size, high accuracy, good reliability, and easy installation. Its performance indicators comply with the national standard GB/T 17215.321-2021 and the power industry standard DL/T614-2007 for technical requirements of electric meters.

It is suitable for electricity control, billing, overload trip, load identification, and other safety management in university apartments. It meets the requirements for branch circuit management in university dormitories, enabling separate metering and control of sockets, lighting, air conditioning, and bathroom circuits to achieve detailed and personalized management.

Features:

1. Dedicated MCU chip for electric meters and high-quality components ensure metering accuracy higher than Class 1.0, with high sensitivity, wide load, and logic anti-tampering features.

2. Standard 35mm rail installation and large-scale integrated circuit design make it compact and easy to install.

3. Large-screen LCD display shows key data in real time, such as total electricity consumption, branch circuit electricity consumption, and branch circuit remaining electricity.

4. Equipped with an RS-485 communication interface and optoelectronic isolation, it effectively prevents destructive interference such as lightning strikes and surges, greatly reducing maintenance difficulty.

5. Three circuits separately manage and control air conditioning, lighting, and socket circuits, featuring timed power-off, overload trip, time-based current limiting, malicious load trip, temperature detection, and infrared control.

6. All three circuits can identify malicious loads and automatically cut off power. The number of trip recovery attempts, malicious load power range, and identification time period are configurable.

7. Three circuits separately meter and manage sockets, lighting, air conditioning, and bathroom circuits, representing the future direction of intelligent electricity usage in apartments.

8. Advanced waveform recognition technology effectively monitors the use of anti-power-limit sockets, addressing the widespread misuse of such sockets in university apartments.

9. Built-in hardware clock supports peak, valley, and flat tariff rates. Multiple tariff periods switch automatically, with data freezing at scheduled times, instant freezing, agreed freezing, and daily freezing.

10. Measures and records current voltage, current, power, and power factor. Records events such as data reset, time calibration, remote power-off, and remote power-on.

11. Powerful embedded software stores operational data and system settings, enabling independent operation and management functions when offline. Strict password verification and security certification ensure safe and reliable data transmission.

12. Compatible with TL645 and MODBUS communication protocols.
