WHAT IS A UPS AND WHAT IS IT FOR
- 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:
- On Line type
- 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.
- 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.
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.
