Overview

Overview: Standard 35mm rail mounted installation, bottom in and bottom out design, using dedicated high-performance MCU chip, with photoelectric isolation RS485 communication interface, LCD liquid crystal display, built-in high-power magnetic holding relay, small size, strong functionality. The performance indicators comply with the technical requirements of the national standard GB/T 17215.321-2021 and the power industry standard DL/T614-2007 for electric energy meters. Mainly used for the construction or renovation of student apartments, employee dormitories, commercial complexes, etc., to achieve remote meter reading, prepayment of electricity bills, low quantity prompts, power outages due to arrears, and safe electricity management and report statistics printing, effectively solving the problem of charging and eliminating safety electricity hazards.

Product Details

1. The dedicated MCU chip and high-quality components for electric meters have a measurement accuracy higher than B (1.0) level.

2. Large screen LCD display, real-time display of key data such as total electricity consumption, used electricity, remaining electricity, etc.

3. The optoelectronic isolation RS-485 communication interface effectively prevents destructive interference such as lightning strikes and surges, greatly reducing maintenance difficulty.

4. Automatic power outage for overdue payments, automatic incoming calls for recharging, and reminders for minimum balance.

5. Remote manual power on/off, timed automatic power on/off, overload tripping, time limited current, malignant tripping, temperature detection, infrared control, air conditioning recognition and other functions.

6. Record time functions such as zeroing, timing, remote tripping, and remote closing.

7. Built in hardware clock circuit, with local data storage, supports remote precise timing and multi rate setting.

8. Measure, record, and measure the voltage, current, power, and power factor of the current module meter; Record events such as zeroing, timing, remote tripping, and remote closing.

9. Autonomous embedded software ensures normal operation when disconnected from the internet, realizing metering deduction and policy control, strict password verification and security authentication, and secure and reliable data transmission.

10. The dual circuit rail smart meter can independently measure and strategically control the two circuits of dormitory air conditioning and lighting sockets.
