Construction of uninterrupted power supply for the equipment room of Vienna base station

An Uninterruptible Power Supply (UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source. In a UPS, the energy is generally stored in flywheels, batteries, or super capacitors.

For larger power units, Dynamic uninterruptible power supply (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 supply fails; an eddy-current regulation maintains the power on the load as long as the flywheels energy is not exhausted.

UPS Definition: A UPS (Uninterruptible Power Supply) is defined as a device that provides immediate power during a main power failure. Energy Storage: UPS systems use batteries, flywheels, or supercapacitors to store energy for use during power interruptions.

An evaluation of the environments, and how a potential UPS system will be deployed, is vital because a lot of environments can support several different uninterruptible power supplies. If you operate in harsh weather conditions for example, then a severe weather UPS power supply may be required.

Once the power is restored, the rectifier begins to charge the batteries. To prevent the batteries from overheating due to the high power rectifier, the charging current is limited. During a main power breakdown, this UPS system operates with zero transfer time.

Be sure to consider how the input power or utility power will be delivered to your most critical equipment. Some electrical equipment may be plugged directly into the UPS. In others, you may require a PDU (Power Distribution Unit) to help distribute the power to computer systems and other electrical apparatus.
