The isolation transformer mentioned here refers to the power frequency transformer working at 5OHz frequency. In the UPS power supply system, the isolation transformer is a main component. According to the difference of UPS circuit structure and power supply system environment, the function and setting method of isolation transformer are also different, so it is not possible to configure isolation transformer in UPS power supply system.

　　Application and selection of UPS power supply

　　We must first understand the function of the isolation transformer and its role in the WS power supply system, and then we can decide when the isolation transformer is not needed and when the isolation transformer must be configured. The function of the isolation transformer in the UPS power supply system. The reason why the isolation transformer is configured in the UPS power supply system is that some are required by the S equipment itself. The transformer is an important part of the dumb heart circuit; Some are set to improve the quality of system power supply; Others are set to match the voltage setting required by the power grid and load equipment.

　　Other factors to be considered include: try to choose brand products. Original products will have factory numbers, instructions and technical manuals, and can feel less noise during operation; Software support. With software support and management, UPS power supply is not just a simple power supply device, but an intelligent device with automatic detection, automatic alarm, automatic storage and other functions. Dabcan, it depends on the specific needs of users; Cooperation with specific application environment, such as the network management ability and cross-platform management ability of power management software should be considered when selecting UPS power supply for networking equipment, while the noise suppression ability and high reliability should be considered when selecting UPS power supply for telecommunication equipment.

　　In a word, when users choose the stabilized frequency and stabilized voltage power supply, they should clarify their own power supply requirements and characteristics, and comprehensively analyze and investigate the UPS power supply of various brands.

Application and selection of UPS power supply and coordination of specific application environment.
