·What is On-line UPS

The operation mode of On-line UPS: When the electricity supply is normal, the electricity absorbed by the filter circuit and the surge, and divided into two loops to take action at the same time, one goes through the charging circuit for battery charging, The other is through the rectifier circuit, as the converter input, and then converted through the converter to provide purified using of the AC power to the load; when an exception occurs in the city electricity, the converter input will be replaced by a battery pack to supply, continue to provide power supply to the power converter to achieve full un-interruption. It can be seen that on-line UPS system output is entirely converted to be supplied by inverter, regardless of how’s the quality of the electricity power, the output are stable and pure sine wave power.
