Uninterruptible Power Supplies (UPS) play a crucial role in ensuring the stability of power supply, and equipment overheating is one of the common alarms that may affect its normal operation. Taking the HIGHIDEA UPS as an example, the possible causes of overheating alarms mainly include: fan failure leading to a decline in heat dissipation efficiency; blockage of the air duct on the rear panel of the UPS, which impedes air circulation; the equipment operating under overload conditions, exceeding its heat dissipation capacity; hardware abnormalities in the NTC temperature sensor or wiring errors causing false alarms; and damage to the power device IGBT resulting in localized overheating.
In response to these issues, HIGHIDEA recommends the following handling measures: First, check whether the rectifier fan is operating normally. If the fan is abnormal, it should be replaced promptly. Second, inspect whether there is dust accumulation or foreign object blockage in the air duct on the rear panel of the UPS. Regular cleaning can ensure smooth ventilation. At the same time, check whether the equipment load exceeds the rated capacity. It is advisable to reduce non-essential equipment or increase the capacity. If the above operations fail to resolve the issue, it is necessary to contact HIGHIDEA's professional technicians to test the NTC sensor and IGBT power devices to rule out hardware failures. Below is an example image of an alarm from a customer's machine.
HIGHIDEA UPS adopts an intelligent temperature control system and an efficient heat dissipation design, which can provide early warnings and reduce the risk of overheating. If users encounter overheating problems, they can receive a rapid response through the brand's after-sales service channels. With a professional technical team and a comprehensive after-sales system, Haideer safeguards the safe operation of users' equipment, ensuring uninterrupted power protection.
