What is the need for a break

Need for an uninterruptible power supply (UPS)

Danger!This chapter is currently being revised so you may encounter temporary inconsistencies or broken links. We strive to carry out the work as quickly as possible and to keep the effects on the user as low as possible. Thank you for your understanding!

Electrical energy from a UPS is provided to prevent a power failure from a storage device based on static batteries or a rotating flywheel mechanism. The reserve operating time of the system is limited and ranges from several minutes to several hours.

By providing a backup power pack and a UPS in parallel, consumers can be continuously supplied where a failure is unacceptable (see Fig.D16). The reserve operating time of the battery or the flywheel must match the maximum start-up and switch-on time of the generator. A UPS can also be used to supply electrical power to loads that are sensitive to electrical interference. (The UPS generates an off-grid voltage.)

When implementing a UPS, the following properties must be taken into account:

The provision of a UPS is essential if equipment is not allowed to fail (but only in this case!).
