: Features a small potentiometer (typically marked "V ADJ") that allows users to fine-tune the output voltage slightly (e.g., ±10%). Circuit Overview
: The circuit initiates oscillation on its own through a pair of Bipolar Junction Transistors (BJTs). Minor biases cause one transistor to start slightly earlier, inducing a voltage in the driver transformer. Controller IC s36012 power supply circuit diagram

The S-360-12 power supply is a masterclass in cost-effective half-bridge SMPS design. Its circuit diagram reveals a robust TL494-driven architecture with proper EMI filtering, over-voltage protection, and current-mode control. By understanding the function of each block—from the input rectification through the driver transformer to the Schottky secondary and TL431 feedback loop—you can confidently repair, modify, or deploy this 360W workhorse. Controller IC Once you master the , you
