Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1*Isolated Power Module 1.Wide Application: MOSFET isolated power module is an electronic device with excellent switching characteristics, widely used in circuits that require electronic switches, such as power supplies, motor drivers, and lighting dimmers. 2.Easy to Use: This switch module operates similarly to the Electronic Building Blocks 4-channel MOSFET switch IRF540. The only difference is that this version has one channel instead of four. 3.Multiple Switches: Our designed 1-channel MOSFET power supply module offers the convenience of controlling four different circuit modules with individual electronic switches. 4.DC Circuit Control: As MOSFET buck converter operate based on their inherent properties, this module is specifically designed for controlling DC circuits. It is not intended for use with AC circuits but excels at providing efficient control over DC-powered devices, like DC LED screens. This specialization ensures optimal performance and safety when working with DC circuits. 5.Easy Connection: The controlled side of the step down module requires slightly more attention during wiring. For example, when controlling a 12V LED strip, connect the power supply between the positive (+) and negative (-) terminals.
