I can help narrow down which part of the circuit is failing.

Uses Schottky diodes (e.g., MBR30100 ) and large electrolytic capacitors (typically 1000µF–2200µF) to smooth the final DC output. Schematic and Service Manual

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. This article provides a comprehensive technical breakdown of

: Utilizes high-power transistors (BJTs or MOSFETs) and a controller like the to pulse-width modulate (PWM) the power. Transformer

Look closely at the secondary side of the circuit diagram, and you will find a small variable resistor (potentiometer) labeled or V+ ADJ . This component tweaks the voltage divider feeding the TL431 reference chip. Turning this physical screw on the power supply casing allows users to safely calibrate the output voltage within a standard range of approximately 10.5V to 13.8V . Cooling Fan Control Circuit

The is a single-output switching power supply. It typically operates on a half-bridge topology without Active Power Factor Correction (PFC). Input: AC switchable. Output:

12V DC (manually adjustable from 10.8V to 13.2V via an onboard trimmer potentiometer)
