Overview

Overview of DDS-315RSII intelligent energy metering module, designed for the trend of air conditioning entering universities, with a one in two out mode, namely two-way metering and two-way control, to achieve separate metering and control of the air conditioning circuit and lighting socket circuit, making electricity management more scientific and user-friendly. This product is mainly used for newly-built or renovated college student apartments, large enterprise employee dormitories, etc. It is easy to install in a layered and centralized manner, occupies a small space, and effectively solves the problem of charging by prepaying electricity bills, low quantity prompts, and power outages due to arrears. It has safety electricity management functions such as current limiting control and load recognition, and eliminates safety electricity hazards. It is the preferred product for promoting scientific management of apartments.

Product Details

1. Dedicated MCU chip and high-quality components for electric meters, with measurement accuracy higher thanB(1.0)It has the characteristics of high sensitivity, wide load capacity, and logic anti submarine.

2. The high flame retardant ABS material shell is dust-proof and moisture-proof, fully sealed, compact in size, effectively utilizes space, and facilitates centralized large-scale installation.

3. Modular independent design, RS-485 communication interface, optoelectronic isolation, effectively preventing destructive interference such as lightning strikes and surges, greatly reducing maintenance difficulty.

4Two circuitsAll have the functions of timed power on/off, automatic power on/off and overload power off according to the set schedule, and time limited current.

5Two circuitsAll of them have the ability to identify malignant loads and automatically turn off the power. The power range of malignant loads can be set, and the identification period can be set.

6. Independently developing waveform recognition technology to effectively monitor the use of anti power limiting sockets and solve the widespread abuse of anti power limiting sockets in university apartments.

7. Built in hardware clock, automatic conversion of multiple rate periods, leap years, and leap months, data timed freezing, instantaneous freezing, agreed freezing, and daily freezing.

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. Embedded software has powerful functions, storing operational data and system settings parameters, and can run independently when disconnected, achieving management functions
