Parts of UPS :

UPS is a electrical equipment which is the group of electrical devices just like as Rectifier, battery, invertor and static switch. The parts detail below mentioned

• Rectifier/ Battery charger.
• Invertor.
• Static switch.
• Display controller.
• Battery bank.

1 - Rectifier/ battery charger: :

Rectifier is an electrical convertor as AC to DC with assistant of diode. Rectifier is used in on line UPS and it also works as battery charger.

2 - Invertor :

Invertor is a convertor which converts DC supply into AC supply. Its works as apposite in comparison of diode. SCR- silicon conductor rectifier are used in inverter. It is the main part of UPS because during power supply switched OFF, It provides the backup supply.

3 - Static Switch :

Static switch is the auto switching device which is used for quick supply changing without interruption. Really it is the brain mind of UPS. It works many mode according condition like as UPS mode, bypass mode. If the UPS is running on supply mode then suddenly inverter is showing alarm so due to this situation, the supply will be changed into bypass mode.

4 - UPS LCD display :

LCD display is a digital monitoring device which is used for controlling and monitoring of UPS. All parameters can be checked easily. A block diagram is shown on display about UPS running status, any alarm and breaker condition.

5 - Battery bank :

Battery is a DC supply storage device which is used for providing DC supply to the inverter. One battery DC supply is 12 volt. A nos of batteries are used as battery bank for improving power backup. Mostly two battery banks are connected in UPS.
