The basic purpose of the Online UPS systems is to protect critical, costly and sensitive equipment from the electrical disturbances that will otherwise jeopardize their operation or affect their performance. Mains Line failures, Blackouts, High & Low Voltage fluctuations, Lightning, Electrostatic discharge and rapid over voltages are phenomenon found in all environments, causing damage to hardware and loss of data. When the mains supply is present, the inverter section derives its power from the mains, rectifies it and the back-up batteries are kept in a constantly charged state. When the mains supply fails, the source of DC Power for the inverter section shifts to the battery without any break whatsoever in the output. |
