Normally, the use of APC UPS power supply may seem simple, but there are actually many things to pay attention to. Some users are often careless and not attentive enough, causing APC UPS power supply to malfunction shortly after use. Only by mastering the scientific usage methods of APC UPS power supply can we avoid damage and failure of APC UPS power supply.
Please do not use under overload. The staff of APC UPS power supply suggest that the maximum starting load of the power supply should be controlled within 80%. If used under overload, the inverter transistor may often break down in the inverter state. Practice has proven that for the vast majority of power sources, controlling their load within the range of 30% to 60% of rated output power is the optimal operating mode;
Do not frequently turn off and on the power supply. Generally, it is required to wait for at least 6 seconds after turning off the power supply before turning it on. Otherwise, the power supply may enter a “startup failure” state, that is, a state where there is neither mains power output nor inverter output;
The placement of APC UPS power supply should avoid direct sunlight and leave sufficient ventilation space. At the same time, it is prohibited to connect inductive loads to the output port; Regularly maintain the APC UPS power supply: remove dust accumulation inside the machine, measure the voltage of the battery pack, replace unqualified batteries, check the operation of the fan, and detect and adjust system parameters;
To ensure the normal operation of APC UPS power supply, it is important that the APC UPS power supply does not operate under overload. Low power UPS power products are different from large APC UPS power supplies in that they have redundant designs and can only operate normally within their nominal output power range. Therefore, if the APC UPS power supply operates under overload, due to the overload protection function of the inverter during the UPS battery power supply process, the APC UPS power supply will interrupt its output due to overload, resulting in unnecessary losses. Proper use of APC UPS power supply is also important to ensure the normal operation and personal safety of APC UPS power supply and its load. Firstly, when the UPS power supply is used for the first time or after a long period of time, it must be connected to the mains power supply to supplement the charging of the USP battery using the APC UPS power supply’s own charging circuit. For low-power APC UPS power supplies, the typical charging time is around 10 hours. Only when the UPS battery capacity reaches saturation can it be put into normal use. Secondly, it is necessary to ensure that the fluctuation range of the mains voltage is consistent with the range of changes in the input voltage of the selected UPS power supply. When connecting the UPS power supply, it is also important to note that the UPS power input must be grounded.
Finally, it should be emphasized that during the use of APC UPS power supply, it is necessary to strictly follow the correct start-up and shutdown sequence to avoid significant voltage output fluctuations caused by sudden load increases or decreases, which may result in the power supply not working properly and shorten the life of power components, or even burn them out.
