For UPS manufacturers, they are also very concerned about the reliability index of their products. The strict requirements of UPS customers will inevitably optimize the selection of UPS materials. For UPS, higher efficiency means lower heat generation, and researchers believe that for every 10 °C rise in temperature, the life of power resistors, capacitors, and other electronic components in electronic products is halved. The reduction in heat generation will contribute to the reduction of the internal temperature of power resistors, capacitors, and other electronic components, thereby increasing the life of power resistors, capacitors, and other electronic components, which means that UPS power supply reliability is also improved.
Second, UPS resistance cost problem
The current UPS power supply prices on the market are different. The lower the cost of the UPS power supply means the lower the UPS efficiency. The cost control often sacrifices the efficiency, reliability or UPS operating temperature of the UPS. In exchange for the UPS cost reduction at the expense of the stability of electronic devices such as precision power resistors and capacitors, the reliability of such UPS power supplies must be reduced. For some power equipment systems, it is unable to withstand the economic loss caused by the low efficiency of UPS power supply. Therefore, it is necessary to use high-level UPS products in purchasing high-end UPS power.
Third, UPS power supply cooling design issues
The reliability of UPS power supply is high, and the internal temperature control of UPS is one of the main factors. However, the external heat dissipation problem is also very important. The UPS power supply should also consider the heat dissipation design of the machine itself. The good heat dissipation design can reduce the temperature and ensure the power resistance, electronic components such as capacitors, stable operating environment temperature control.
