Uninterruptible power supply, is a small box, one attached to the AC, a computer and other computers need to continue to do when the power to save the work of electronic products, which charge the power, the ordinary UPS can also be used when the power 2-20 minutes or so.
UPS (Uninterruptible Power System), that is, uninterruptible power supply, is the battery (mostly lead-acid maintenance-free battery) connected with the host, through the host inverter and other modules to convert DC power into the main system equipment The
Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters, etc. to provide a stable, uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.
