Tips for dust cleaning with UPS power supply

In the environment where UPS power is used, there will be more or less dust. People usually maintain UPS power supplies and focus on the mainframe and UPS batteries. These small dusts may sometimes be ignored. In fact, the accumulation of dust has a great impact on the UPS mainframe.
In some areas with dry climates, because there is more dust in the air, the fan in the UPS main unit will bring the dust into the unit and precipitate. When the air is humid, it will cause the control of the main unit to be disordered and cause the main unit to work abnormally and give false alarms. A large amount of dust will also cause poor heat dissipation of the UPS power supply, leading to an increase in the temperature inside the machine, affecting the service life of the UPS power supply, and more serious, causing the UPS host to explode. Therefore, attention must be paid to UPS dust removal. 

Generally, UPS equipment must be overhauled every four years. Firstly, replace all fans of the UPS. Then, according to the operating conditions, a professional will check the ripple of the DC loop with power on, and check whether the DC capacitors and AC capacitors are abnormal from the outside. , Use a special meter to test the capacity of the capacitor to determine whether to replace the capacitor. The cleaning method is to start reinstalling the plug-in after the cleaning and maintenance are completed. Pay attention to the plug-in tightly and the secondary plug to be plugged in. Check whether the fan and the cover have resonance after power on. If all the above conditions are normal, the UPS will continue to manually bypass the power supply load. In the case of no load, professional and technical personnel will separately supply power to the UPS to debug the automatic bypass, rectifier and inverter. If the debugging is normal, the UPS starts to switch, from manual bypass to automatic bypass and then to the inverter to supply power. Secondly, when removing dust, check whether the connectors and plug-ins are loose or not in firm contact

In addition to these dust removal tips, when you see dust on the UPS main unit in the process of using the UPS power supply, you should also develop a cleaning habit so that the dust will not accumulate and keep the UPS main unit clean for a long that provide a better, more stable and reliable power supply.
