Using the schematic, you can troubleshoot known issues:
takes over to regulate the switching process. This IC manages the duty cycle of the power transistors to maintain a steady output voltage via Pulse Width Modulation (PWM) Power Switching

Unlike simpler layouts, the S-360-12 features a distinct auxiliary startup circuit designed to power this chip safely.
The filtered AC voltage is then sent to a bridge rectifier. This is typically a four-diode bridge or a single integrated bridge IC (e.g., DB107) that converts the AC voltage into a high-voltage pulsating DC. A large, high-voltage electrolytic capacitor then smooths this pulsating DC. The primary capacitor for the S-360-12 is typically rated for 400V with a capacitance of around 100-220µF. At this point, you will have a steady DC voltage of approximately 310V (from a 220V AC input). Using the schematic, you can troubleshoot known issues:
Below is a breakdown of the critical stages you will find in a schematic diagram of the S36012 board.
Before delving into the circuit diagram, it is crucial to establish the key parameters that define the S-360-12's capabilities. These specifications are the performance boundaries within which the power supply is designed to operate reliably. The filtered AC voltage is then sent to a bridge rectifier
