1.1Theory of Operation

An Uninterruptible Power Supply (UPS) is a system that is installed between the commercial power and the critical load. The UPS provides steady AC output power during commercial power fluctuations and interruptions.

During “Normal Operation” the UPS utilizes commercial AC power and removes high voltage spikes and transients caused by switching and faults on the utility. The result of this process is maximum power conditioning and regulation.

If the AC power supplied to the UPS drops below a specified voltage level, the unit's batteries automatically begin supplying power instead of receiving it. This insures that the loads connected to the UPS continue to receive power without interruption. This power is provided for a long enough time so that the load can be shut down in an orderly fashion. This prevents loss of data and possible damage to both hardware and software.

When the AC input power becomes available again, the operation returns to normal and the batteries begin to recharge for the next power interruption.

1.2Application and Use

Toshiba's 4200FA On-Line, Uninterruptible Power Systems (UPS) provide continuous computer grade isolated AC power in a compact, efficient, high performance unit. The UPS assures safe, reliable operation of critical office equipment, ranging from personal computers to mini-computers to local area networks (LAN). All units feature an audible alarm that sounds if the battery voltage drops below the standard during use. This is an additional aid to help in retaining valuable data and equipment. All units are capable of interfacing to a computer network.

1.3Power Backup

During an electrical power failure the UPS batteries automatically supply DC power to the inverter that supports the load equipment, without interruption. For example, when used to support a computer, the UPS’s back up assures additional time to complete your activity, store data and initiate an orderly shutdown after a power failure occurs.

1.4 Power Conditioning

While commercial power is present, the UPS supplies conditioned power to the load while maintaining its batteries in a charged condition. The UPS protects the connected load against the normal, everyday problems associated with heavy use of raw commercial power, including power sags, surges, signal interference, and spikes. In addition, the models with transformers provide total isolation to reduce the common and normal mode noises. This adds further protection to keep power-line problems from reaching your load, where it can cause equipment to operate erratically, or damage hardware and software.
