Uninterrupted power supply units store power in a UPS battery during the times when there is regular utility power flowing to the devices that it is protecting. If the utility power shuts off or is disconnected, the UPS will continue to deliver a steady stream of electricity to the devices.
Uninterruptible power supply (UPS) devices provide a continuous supply of electricity to equipment that is connected. A uninterruptible power supply is placed between utility power and the devices that are to receive UPS power if the main utility power is interrupted.
Though UPS devices have been very expensive throughout history, they have become very affordable over the last couple of decades. Now, UPS units are commonplace in home offices, data centers and businesses everywhere.
You can buy an uninterrupted power supply for a single computer that isn’t even strong enough to power the monitor, or huge UPS devices to power entire data centers for large companies.
The North American Blackout of 2003 was probably the single most impressive event that more recently has helped many people to reconsider their need for an uninterrupted power supply for their offices.
The biggest attraction to and use of UPS units is o protect data. Everywhere people have sensitive information that they don’t want to loose due to a storm or power outage.
There are also many applications where UPS devices are put in place to safeguard lives. In hospitals and other medical care facilities, uninterrupted power supplies are waiting in back up to run life support machines and all sorts of devices and systems that are keeping animals, plants and people as alive and healthy as possible.
