Rapidly turns the MOSFET on and off at high frequencies (e.g., 65 kHz). By varying the duty cycle (pulse-width modulation), it accurately maintains the output voltage under varying load demands. 4. Secondary Side Rectification and Output Filtering

Supplies power when the relay is at rest (not energized). 3. F4901 11A 24V Schematic Diagram

For AC-to-DC conversion, the F4901 schematic relies on a high-current bridge rectifier. 24V Power Supply Circuit | 9 Circuits - ElecCircuit.com

Core schematic elements

If you look at any standard 24V relay PCB, you will see a diode (typically a 1N4007) wired in parallel with the relay coil, pointing opposite to the current flow. This is a . When the 24V power is cut, the magnetic field in the coil collapses, generating a massive high-voltage spike. The diode safely shorts this spike, protecting the control electronics from burning out. 3. The Power Contacts (The Load Circuit) 24V Power Supply Circuit | 9 Circuits - ElecCircuit
