Tips: What is an UPS (Uninterruptible Power Supply)? And how it works?
UPS (Uninterruptible Power Supply) is system equipment that converts the direct current of battery to the utility power through dc-to-ac converter and other modular circuit of main engine by connecting storage battery (most are lead-acid maintenance free storage battery) to the main engine. It is mainly used for providing stable and continuous power supply to personal computers, computer network systems or other power electronic devices. Generally, the UPS has a wide range of capacity, like 600VA/300Watts, 1000VA/600Watts, etc. for different applications.
When the mains supply is normal, it will be provided for load use after the voltage stabilization by UPS. The uninterruptible power supply plays a role of an AC voltage regulator at this time. Meanwhile, it also recharges the battery inside. When the utility power fails (unscheduled interruption), the UPS will immediately supply the 110V/220V AC to the load by converting the DC power of the battery with help of the inverter, to make sure that the load can keep normal operation and to protect the load software and hardware from being damaged.
