What is the uninterruptible power supply?
UPS (Uninterruptible Power System/Uninterruptible Power Supply), namely, uninterruptible power supply, the battery is (for maintenance free lead-acid batteries) connected with the host, the host through the inverter module circuit of the direct current into power system equipment. Used primarily to provide stable and uninterrupted power supply to a single computer, computer network system, or other power electronic equipment.
When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS immediately DC battery energy conversion method by zero switching inverter continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices are usually protected against high voltage or low voltage.
It's UPS.Plainly, the battery charging loop + Battery + inverter device. Generally, the charging device and the inverter of the battery are arranged in a box body, and an external battery is connected, so as to form an uninterrupted power supply.
