Design of 1000 VA capacity uninterruptible power supply (UPS) for server room at film sensor institutions of the Republic of Indonesia.

A server room is a room that is used to store applications, data, network devices, and other devices related to daily system operations. Data on the server room is required at all times so it should not be disturbed. PLN's electrical energy is the main source of electrical energy in the server room at the Indonesian Film Censorship Institute (LSF). An uninterruptible power supply (UPS) is an electronic device that can provide a temporary backup supply of electricity when the main electric current (PLN) is cut off or out. The UPS is designed to use a step-down CT transformer to step down the voltage from 220 VAC to 24 VAC. Rectifier to rectify AC voltage into DC voltage. 48 V 2 A charger circuit to charge dry batteries. A dry battery is needed as backup power when the power from PLN goes out. Then there is an inverter circuit that is used to convert DC voltage into AC voltage. A static switch that functions as a switching switch from normal operation mode to bypass operation automatically and otherwise. The rectifier module is connected to a transformer as a voltage source. The charger module is connected to the rectifier module as a voltage source and the output of the charger module is connected to the dry battery and inverter module. The inverter module is connected to the voltage provided by the charger module and dry battery. The static switch input which is used as the switching switch from the UPS main system to bypass mode is connected to the inverter module, and its output is connected to the PZEM- 022 LCD panel, the fan, and load that will be used later. The tool that is designed works well to provide voltage to the load when PLN is on or when PLN is off. [ABSTRACT FROM AUTHOR]
