How To Size An Uninterruptible Power Supply
Properly sizing an Uninterruptible Power Supply (UPS) is crucial to ensure the optimal performance and reliability of your electrical devices. Sizing refers to determining the
Calculate the appropriate uninterruptible power supply (UPS) size by entering your equipment power requirements and backup needs below. This calculator helps determine the correct UPS capacity in VA (Volt-Amps) and required battery runtime based on your connected load and desired backup duration.
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
Not all equipment needs to be supported, so reviewing all your equipment and breaking it down into a list of either critical load or non-critical load can help make sure your final uninterruptible power supply size requirement is not drastically oversized.
For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
