Today most of the products used by us require electricity to operate or in other words electronics products are in great demand and most of the household products are electronic based. To lure the customers various companies are launching latest technology based products that are high in features and functionalities. These sophisticated electronic products requires great amount of care and protection in order to efficiently operate for longer period of time. Latest technologies are used not only to manufacture these products but it is also used to protect these sophisticated products. One such product is standby power supply that takes care of electrical equipment and saves them from power breakdown, blackout, brownout, surges, spikes and many others power problems. However standby power supply is mostly used with computers where sudden power failure can corrupt your important files or data. Hence with standby power supply power is provided for few minutes that help to properly shut down the computer.

Standby power supply help to keep electrical devices running for few minutes and provides the necessary power from the battery source at the time of power failure. It not only provide power to electrical devices for properly shutting down but also protects the devices from power fluctuation and other power failures that can cause damage to the devices. In standby power supply the primary power source is the line power from the utility whereas battery is considered as secondary power source. In normal condition the electrical devices are getting power from the main utility source and the standby power supply comes in function only after the main power break down.

Standby power supply function is different from UPS as it does not provide continuous power to the load. Infact a standby power supply is similar to line interactive UPS where the inverter is not supporting the load instead it provides power when there is a power break down. Standby powers supplies are low cost products and provide minimum level of voltage regulation and line conditioning. Standby power supply provides power from a battery that is charged through the inverter. The inverter does not supply power to electrical equipment but it charges the battery and wait in anticipation to be used in case of power breakdown. Standby power supply is the best alternative as it provides power without any fault through the power outages. The backup time provided by the standby power supply depends on the wattage requirement. In order to provide protection, a standby power supply is used that power these products for few seconds so that they can be properly shut down or closed.
