S36012 Power Supply Circuit Diagram Updated -

| Protection | Circuit Method | Action | | :--- | :--- | :--- | | | Current sensing via a 0.01Ω/5W wirewound resistor on the negative output rail. Voltage across it is fed to pin 16 (Error Amp 2) of TL494. | If voltage exceeds ~0.3V (≈30A), TL494 shuts down output. Hiccup mode. | | Over-voltage (OVP) | A Zener diode (13V) + SCR (C106) across output. | If output >13.5V, Zener triggers SCR, shorting output and blowing the primary fuse. | | Over-temperature | NTC thermistor bonded to the main heatsink, connected to TL494 shutdown pin. | Shuts down at >85°C. Automatically resumes when cool. |

The is a widely used 360W switching power supply (SMPS) that converts 110V/220V AC to a regulated 12V DC output at up to 30A. It typically utilizes a half-bridge topology, often controlled by a TL494 or KA7500 PWM integrated circuit. Circuit Diagrams | Protection | Circuit Method | Action |
