1. Power industry: Power supply guarantee for DCS control system of thermal power plant units and auxiliary system of nuclear power plants. When the plant power supply is interrupted, the module immediately switches to backup power supply to ensure the continuous operation of key circuits such as boiler water level control and turbine regulation, avoiding unit tripping or equipment damage.

2. Chemical industry: When the main power supply is interrupted, the emergency shutdown system (ESD), regulating valve, and toxic gas detection equipment of the reaction kettle control unit and toxic and harmful medium conveying system of large-scale chemical plants are guaranteed to continue working, preventing reaction loss of control or toxic medium leakage.

3. Oil and gas industry: The control system of oil and gas drilling platforms and the SCADA system of long-distance pipelines provide power supply. In the event of unstable or sudden power outages in the field power grid, they provide backup power for controllers, communication modules, and emergency shut-off valves to ensure drilling safety or the continuity of pipeline transportation.

4. Metallurgical industry: Power supply for control systems of key production equipment such as converters and continuous casting machines in steel plants. When the main power supply is interrupted, ensure stable control of core parameters such as temperature control and crystallizer vibration to avoid equipment scrap and production interruption caused by steel solidification.

5. Data Center and Municipal Dispatch: Industrial data center servers and municipal emergency dispatch systems are powered. In the event of a main power failure, the continuity of data storage and transmission is ensured to avoid data loss, while ensuring the normal issuance of emergency dispatch instructions.

Key points for installation and maintenance

5.1 Installation specifications

-The module should be installed in a control cabinet with a protection level of IP20 or above to prevent the intrusion of dust, water vapor, and corrosive gases; The control cabinet needs to reserve sufficient ventilation space, with a spacing of ≥ 15mm around the modules to ensure good heat dissipation and prevent module performance degradation caused by high temperatures.

-Before installation, it is necessary to set the input voltage (110V AC or 230V AC) through the dip switch on the side of the module according to the specifications of the main power supply voltage on site, to avoid voltage mismatch and module burnout.

-The input and output wiring must be strictly distinguished: the main power input line uses copper core cables (cross-sectional area ≥ 2.5mm ²) and is equipped with air switches (rated current 16A); The output line adopts multi stranded copper core wire (cross-sectional area ≥ 4mm ²) to avoid high current causing heating of the circuit; Attention should be paid to the positive and negative polarity of battery wiring, and reverse connection is strictly prohibited.

-The communication line adopts shielded twisted pair cables, with the shielding layer grounded at one end (grounding resistance ≤ 4 Ω), and is separated from the strong current cable for wiring (spacing ≥ 30cm) to avoid electromagnetic interference affecting communication stability; When multiple modules are connected in parallel, they need to be connected through dedicated synchronous cables to ensure load sharing.

-The module installation needs to be firmly fixed to avoid loose wiring caused by vibration; The installation location should be far away from strong electromagnetic interference sources such as frequency converters and high-power motors to reduce the impact of interference on module switching performance.

5.2 Maintenance Suggestions

-Daily status check: Observe the module status indicator light daily. During normal operation, the "power light" and "running light" are always on, and the "battery light" is always on when the battery is normal; If the "fault light" is on, the fault type (such as overvoltage, battery failure, etc.) needs to be checked immediately through the control system.

-Battery maintenance: Check the appearance of the battery every month (without bulges or leaks), and measure the battery terminal voltage (normal float charge voltage 13.5V~13.8V); Conduct a 'discharge test' once every quarter, disconnect the main power supply and let the battery power for 30 minutes to check if the battery capacity meets the requirements. Replace the aging battery once a year.

-Electrical parameter calibration: Use a high-precision multimeter every six months to calibrate the output voltage of the module, ensuring that the output accuracy is within ± 0.5% range; Check if the switching time is ≤ 5ms, and monitor the voltage waveform at the moment of switching between the main and backup power sources through an oscilloscope.

-Fault handling process: When the module alarms, first disconnect the main power supply and check if the input voltage is normal; If it is a battery failure, replace the battery and reset the module; If it is an output overcurrent, check whether the load is short circuited, eliminate the fault, and then close it again; If there is an internal malfunction in the module, it is necessary to contact professional personnel for repair and self disassembly is prohibited.

-Environment and cleanliness: Clean the dust on the surface of the module and inside the control cabinet every month, and keep the ventilation openings unobstructed; Check the operation of the cooling fan during the high temperature season (if equipped), and install moisture-proof devices in humid environments to prevent the internal circuits of the module from being corroded by moisture.
