Background
An Uninterruptible Power Supply (UPS) is an Uninterruptible Power Supply (UPS) that includes an energy storage device. The power supply device is mainly used for providing uninterrupted power supply for partial equipment with higher requirements on power supply stability.
When the commercial power input is normal, the UPS supplies the commercial power to the load for use after stabilizing the voltage, and the UPS is an alternating current type voltage stabilizer and also charges the battery in the machine; when the commercial power is interrupted (power failure in accident), the UPS immediately supplies the direct current electric energy of the battery to the load by a method of switching and converting the inverter to continuously supply 220V alternating current to the load, so that the load keeps normal work and the software and hardware of the load are protected from being damaged. UPS devices typically provide protection against either excessive voltage or insufficient voltage.
An Uninterruptible Power Supply (UPS) is a system device that connects a battery (mostly a lead-acid maintenance-free battery) to a host and converts direct current into commercial power through a module circuit such as a host inverter.
