S36012 Power Supply Circuit Diagram |link| -

The "hot side" of the S360-12 contains across the bulk capacitors. This voltage can remain present for several minutes after the power is disconnected. Always discharge the main capacitors before touching the underside of the PCB.

Usually a pair of 13009 NPN power transistors. These turn the high-voltage DC into a high-frequency AC signal (usually 50kHz–100kHz).

Most S360-12 units use a thermal switch or a simple transistor circuit to kick the cooling fan on only when the internal heatsink reaches ~45°C. Safety Warning s36012 power supply circuit diagram

A combination of X/Y capacitors and a common-mode choke to prevent high-frequency noise from leaking back into your wall outlet.

Understanding its circuit diagram is essential for anyone looking to repair, modify, or integrate this unit into a custom project. Core Architecture: The Half-Bridge Topology The "hot side" of the S360-12 contains across

Limits the "inrush current" when you first flip the switch.

Most S360-12 units utilize a . Unlike simpler flyback converters, the half-bridge design is more efficient for high-power applications (above 150W), as it balances the load across two main switching transistors. 1. Input Stage (EMI Filter & Rectification) Usually a pair of 13009 NPN power transistors

A large ferrite core transformer that steps the high-voltage AC down to low-voltage AC. Because the frequency is so high, this transformer can be much smaller than a traditional 60Hz transformer. 4. Output Rectification & Filtering
