Description

Each power module generally includes a housing, and the housing contains a high-voltage coil and a low-voltage coil for voltage conversion. However, in general, multiple power supply modules are used, and each power supply module has an empty space inside the shell, so the sum of it takes up a lot of space in the cabinet.
