Tips: What is UPS?UPS (Uninterruptible Power Supply) is system equipment that converts the direct current to electric supply through main engine dc-to-ac converter and other modular circuit 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 single computers, computer network systems or other power electronic devices, such as solenoid valves, pressure transmitters, etc. When the electric supply input is normal, after the voltage stabilization of the electric supply, it will be provided for load use by UPS. The UPS is an AC electric voltage regulator at that time. At the same time, it also recharges the battery. When the electric supply breaks off (unscheduled interruption), UPS will immediately supply the 220V AC to the load by converting the DC power of the battery and switching the inverter, so that the load can maintain normal operation and protect the load software and hardware from being damaged. UPS devices usually provide protection for high voltage or low voltage.
