Power Online & Offline UPS
Online UPS and Offline UPS are the two crucial types of UPS. Both supply power to the device in case of power outage. But the similarities end here. The main difference between Online UPS and Offline UPS is that the Online UPS provides the power with the help of rectifier and inverter combination. It simultaneously provides power to load as well as the battery so that battery can be charged to supply power in case of power failure.
Most standby power systems will involve the use of an uninterruptible power supply (UPS). The UPS either carries a load to allow data to be saved and systems to be shut down correctly, or it acts as a bridge between the mains failure and a longer-term backup supply, such as a generator.
Things to consider choosing the right UPS:
High frequency and double conversion on-line technology.
Digitized microprocessor control optimizes reliability.
Wide input voltage range
Lightning & Surge protection
Short circuit and overload protection
Advanced battery management
Automatic battery charging in UPS offline mode.
Online UPS
An online UPS is the one in which the inverter always supplies power to the protected load and hence the same quality of power is ensured all the time.
Offline UPS
The offline UPS supplies (or routes) the incoming mains supply directly through to the output usually through a relay contact.
