1.Fault phenomenon: UPS cannot charge, resulting in the inability to provide backup power during power outages.
Solution: Check if the UPS battery is damaged. If the battery is damaged, it needs to be replaced. Additionally, check if the UPS charging circuit is functioning properly. If the charging circuit is abnormal, contact a professional for repair.
2.Fault phenomenon: UPS frequently switches to battery mode, resulting in shortened battery life.
Solution: Check if the input voltage of the UPS is stable. If the input voltage is unstable, the power supply issue needs to be resolved. Additionally, check if the UPS battery is aging, and if it is, replace the battery.
3.Fault phenomenon: UPS uninterruptible power supply cannot work properly, resulting in computers and other equipment not being protected.
Solution: Check if the input voltage and output voltage of the UPS are normal. If the voltage is abnormal, check the power circuit and UPS power board. In addition, check if the UPS settings are correct. If the settings are incorrect, they need to be reset.
4.Fault phenomenon: UPS uninterruptible power supply has excessive noise, affecting the working environment.
Solution: Check if the UPS fan is working properly. If the fan is abnormal, it needs to be replaced. In addition, check the heat dissipation of UPS and improve ventilation conditions if there is poor heat dissipation.
5.Fault phenomenon: UPS cannot start automatically, resulting in computers and other devices not being protected during power outages.
Solution: Check if the UPS settings are correct. If the settings are incorrect, they need to be reset. Additionally, check if the UPS battery is damaged, and if it is, replace the battery.
In summary, common UPS malfunctions include inability to charge, frequent switching to battery mode, malfunction, excessive noise, and inability to start automatically. For these faults, timely inspection and handling are necessary to ensure the normal operation of UPS and protect the safety of computers and other equipment.
