UPS: Uninterruptable Power Supply

UPS is an electric device which provides clean, reliable, AC power to your computer and peripherals and also protects them from power sags, surges, blackouts, brownouts and interface. It also gives some backup on power cut, the backup is depend upon how much peripherals we are using on it. Normal UPS give backup time from 20 minutes to more than 30 minutes.

Function of normal UPS operates on Mains, supplying power to the load from the utility input. The battery charger uses the Mains power to keep the battery at an optimal level. When the power fails or cuts, the UPS transfers the load to the battery. The UPS converts the battery’s DC power to AC power on power failure. There load operate normally until shutdown or until the battery is exhausted, the battery backup duration depend on capacity of UPS. The Load is automatically transferred back to the utility when the normal Mains restores. The UPS also provides surge protection and filtering as well as output voltage regulations which increases under voltage and reduces over voltage conditions. It works like stabilizer. The optional software allows UPS device to communicate with computer for auto shutdown. Due to this UPS works like safe guard for your computer and peripherals. Without UPS if we work on computer for your valuable work and suddenly power cuts then UPS give us some time to save your important safely and if you are not using such backup devices then there is risk of data loss on power cut.

• Connect the UPS to a three-wire grounding Mains socket. The socket must be connected to appropriately protected branch of fuse or circuit maker. Connection to any other type of socket may result in a shock hazard and damage to UPS.

• UPS has battery inside which acts as an energy source and output may be available even when the unit is not connected to a mains supply, remember backup duration is depend on capacity of the battery inside.

• To switch off the UPS output in an emergency, use the switch on front to switch on front to switch the UPS off. And disconnect the power cord from the Main switch.

• Avoid installing the UPS where there is water or excessive humidity or liquid content. The unit should be kept away from heat-emitting appliances such as a heater, blower, oven etc. Exposure to direct sun light should be avoided. The place of installation should be well-ventilated and easily accessible for serving.

• Don’t try to open the case of UPS if you don’t have the knowledge of solving UPS problems.

• Water or foreign objects should not get inside the UPS. Do not object containing liquid on or near the unit.
