Why Does the Automatic Control System Use UPS Power Supply

For industrial production, the power supply quality of its industrial control system plays a vital role in the efficient and reliable operation of enterprise production and communication. Therefore, this paper starts with the popular UPS power supply at present, considers the important position and role of UPS power supply in industrial control system through the systematic cognition of UPS power supply structure and working principle, and explores the UPS power supply selection principle of industrial control system in actual industrial production.

The automation control system includes electromechanical technical services, PLC program (program) design, change, servo control system design and installation, frequency conversion control system design and installation, motor control system design and installation, hydraulic and pneumatic control system design and installation, electric heating control system design and installation, gas heating control system design and installation, electromechanical technical services.

Among them, UPS power supply needs to be configured in PLC program, servo control system, frequency conversion control system, motor control system and hydraulic pneumatic control system. If the outgoing line in PLC system is powered off, the whole production will be paralyzed. PLC must be equipped with UPS power supply.

Causes and Solutions of UPS Power Supply Dripping All the Time
The machine itself has a certain noise list. If the environment is cleaner, the noise list after maintenance is smaller. If it is an alarm sound, there are many situations, such as battery power supply after power failure, battery power supply caused by unstable voltage, and alarm in case of machine failure, etc.UPS (uninterruptible power system), namely uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains power input is normal, ups will stabilize the mains power and supply it to the load. At this time, UPS is an AC mains power regulator, and it also charges the battery in the machine; When the mains power is interrupted (emergency power failure), ups will continue to supply 220V AC power to the load through inverter conversion, so as to maintain the normal operation of the load and protect the software and hardware of the load from damage. UPS equipment usually provides protection against over voltage and too low voltage.Causes of UPS power supply dripping all the timeThere are several reasons:1、 Prompt tone:1. During startup and shutdown, a "drop" sound informs that the key is turned on or off successfully.2. Using the "drip" sound with a long interval (about 5 seconds) is to inform that the power is supplied by the battery. At this time, there may be two situations: one is that the mains power has been interrupted, and the other is that the mains voltage is too low and the battery is supplying power.3. The continuous and rapid "drip, drip" sound indicates that the battery is about to run out and the UPS is about to shut down automatically.Different UPS designs have different prompt tones, and the prompt contents are expressed in various ways. Some use indicator lights, some use voltmeters and ammeters, and others use small-size display screens.2、 Noise.1. The sound of cooling fan is unavoidable, especially for high-power ups. Of course, when it is found that the sound is louder than that when it is newly purchased, dust removal should be carried out, especially the dust on the fan blades and the protective net.2. Buzzing. The power frequency sine wave is output to UPS, and there is a large transformer inside. When the battery power supply is restored to the mains power supply, it is necessary to meet the output and charge the battery. The transformer works at full load, emitting 50 cycle AC hum, resonating with the chassis and buzzing. This happened at a special time.3. Irregular crackle and crackle, which is likely to have a fault. At this time, carefully observe it and stop the machine for inspection if necessary.Usually, you should be familiar with the characteristics of the UPS used and be able to deal with situations calmly.Solution to dripping sound during UPS power supplyUPS is originally a backup power supply for short-term power supply. The beep of "didi" means that the power grid has stopped power supply and is now switched to DC power supply. Due to the extremely limited internal battery capacity, it can only maintain power supply for a few minutes. This beep of "didi" is just to remind users to hurry up and store data, To avoid the loss of unsaved data due to 'forced' power failure.Generally, the buzzer is directly welded on the main board; There are solutions: 1. Use an electric soldering iron to heat and disassemble, and the sound disappears completely. 2. Stick the sound outlet of the buzzer with self-adhesive, and there is still sound, but it is significantly reduced.In theory, this makes no sense, because UPS can only provide you with power for a few minutes.This can also be solved additionally. Just use a large battery, and the voltage should be consistent with the battery in the machine.
