MOSFET 4-way Electronic Block Switch IRF540 Isolated Power Module Isolation IRF540 Isolation Power Module Electronic Block 4 Channel IRF540 MOSFET Switch Module 4 Channel MOSFET Power Module Electronic Block Up to four groups of electronic switches can be supplied by the switch to regulate various circuit blocks. One electronic device with good switching properties is the MOSFET. Power supply switching, motor drives, lighting dimmers, and other circuits use it extensively. Due to its limited operating principles, MOSFETs are only appropriate for controlling DC circuits, such as DC-LED screens, and are not appropriate for controlling AC circuits. It can be used to regulate the 100V/33A DC circuit in certain extreme situations. Nonetheless, it is recommended that the regulated DC voltage is
