An uninterruptible power supply (UPS) is a type of electrical equipment used to provide continuous and stable power in the event of a power outage or power fluctuation**. UPS works by converting electricity from the grid to direct current, storing it in a built-in battery, and then converting it into alternating current** to connected devices. This conversion process can be started immediately in the event of a power outage to ensure continuous operation of the device and avoid data loss, device damage, or business interruption.
UPS usually consists of a rectifier, an inverter, and a battery. The rectifier converts alternating current to direct current and is used to recharge the battery, while the inverter converts the direct current stored in the battery into alternating current** to the device. The UPS is also equipped with monitoring and protection functions that can monitor power quality, battery status, and equipment load, and provide alarm or automatic shutdown protection if necessary.
UPS is widely used in various fields, including data centers, communication base stations, medical equipment, industrial automation, financial institutions and other places with high requirements for power. They provide stable power assurance for critical equipment, ensuring that equipment can continue to operate in the event of a power failure or power outage, protecting data security and business continuity.
