WHAT IS A UPS AND WHAT IS IT FOR

UPS

• UPS is the abbreviation of Uninterruptable Power System, (Uninterruptible Power System).
• It is used to electrical equipment
• is costly
• both in time
• due to loss of information or damage to its components.

UPS TECHNICAL PARTS:

• Rectifier that rectifies the alternating current input
• providing direct current to charge a battery.
• From this it is fed to an inverter that converts it again into alternate.
• After having discharged the battery, it is usually recharged in a time of 8 to 10 hours
• The capacity of the charger should be proportional to the size of the battery needed.

There are several types of ups that are:

1. On Line type
2. Stand By

On Line type

• The current passes through the rectifier permanently
• charges the battery and also supplies the Inverter
• which in turn supplies the output with alternating current.
• If the input voltage is cut, the batteries continue to power the inverter
• That the output does not suffer any interruption due to the cut.
• The rectifier must be sized to provide more power than the inverter
• since it must also recharge the battery after a discharge.
• Both must be able to work with all their power permanently.

Stand By

• Where the Switch is normally connected to the input line (By Pass)
• bringing the energy from the input directly to the output (usually through a voltage stabilizer and line filter).
• If the input voltage is cut, the switch connects the output to the inverter
• which starts to work instantaneously, feeding the output from the batteries.
• Since the input line is cut (or out of normal range) until the 220 Volts supply is restored to the output
• a time of the order of 5 milliseconds (or ¼ cycle) passes.

Conclusion

This type of UPS is widely used in ARVI UPS; they are used to be able to store the files of computers if there is a power outage for example giving a time of electricity. Depending on how large the equipment is, you will have more or less alternative energy time.
