UPS power supply is mainly used to prevent the damage to equipment caused by sudden power failure, ensure the normal operation of electronic equipment, and avoid problems such as failure or data loss caused by power fluctuation, instantaneous power failure and overvoltage.
UPS power supply converts commercial power into constant direct current, which is stored in storage battery for equipment use. Under normal circumstances, after the mains power is rectified and filtered, UPS converts it into constant DC power and charges the battery at the same time. When the mains power fails (such as power failure, overvoltage, etc.). ), the UPS power supply can immediately detect and automatically switch to the battery power supply state, so as to ensure that the connected electronic equipment will not be damaged due to sudden power failure.
Advantages of UPS power supply:
1, stable
The advantage of UPS power supply is that it can provide stable power supply for equipment. When the mains power supply is unstable, the UPS power supply can be automatically switched to the standby power supply, so that the equipment can work without interference. Therefore, UPS power supply is widely used in key equipment that needs long-term operation, such as servers, communication equipment and medical equipment.
2. Protective equipment
UPS power supply can also provide protection for equipment. When the mains power supply is unstable or cut off, the equipment is easily affected by voltage jump or excessive current, resulting in hardware failure or data loss. UPS power supply can be switched to standby power supply in time to protect equipment from these problems.
