[0001] The utility model relates to the technical field of isolated power supplies, in particular to a universal isolated power supply. Background Art

[0002] An isolated power supply is a power supply in which there is no direct electrical connection between the input circuit and the output circuit. The input and output are in an insulated high-impedance state and there is no current loop. For the power supply of remote industrial communications, in order to effectively reduce the impact of ground potential difference and wire coupling interference, an isolated power supply is generally used to power each communication node separately.

[0003] The isolated power supply needs to use an isolated power chip. The pins of most existing isolated power chips are fixed on the isolated power chip by welding. However, when installing the isolated power chip for different electrical equipment, it is necessary to use an isolated power chip with specified pins. Therefore, when the isolated power chip is produced, it is necessary to install the pins of the isolated power chip in different positions according to different electrical equipment, which increases the trouble of producing the isolated power chip. Therefore, we propose a universal isolated power supply. Utility Model Content
