What is the UPS line of online and off-line work?
UPS power online work: that is, in the case of power failure is not broken.
Offline work is, there is a power outage, then the power saved by the UPS power to make the machine continue to work. UPS this work is called off-line work.
UPS is an abbreviation for Uninterruptible Power System. That is, uninterruptible power supply system. When the mains input, UPS will be the mains after the power supply to the load, while the battery charging the machine, the energy stored in the battery, when the electricity interruption (accident power failure) or input failure, UPS immediately Internal battery energy conversion to 220V AC continue to be used for load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged
★ ON-LINE UPS
Features: 1. Output to the load of the power by the UPS treatment, the highest output power quality
2. No conversion time
3. Complex structure, high cost
4. The highest protection, the mains noise, surge attenuation ability of the best

Backup UPS (Off line): When the electricity is normal power supply, the mains through the AC bypass channel and then through the transfer switch is sent to the user load. In the early backup UPS, this AC bypass channel is actually a wire. In recent years, the backup UPS, often equipped with a transformer plug regulator simple exchange voltage regulator circuit. When the electricity is abnormal when transferred to the battery-powered state.
Easy to answer, online: the inverter in the work, and charging, and power supply. Offline: the inverter is not working properly, power to work, only charge.
