Unlike simpler layouts, the S-360-12 features a distinct auxiliary startup circuit designed to power this chip safely.
: Uses power NPN transistors (often 13009 series) to drive the main transformer at high frequency. s36012 power supply circuit diagram
If you are looking at an S360-12 circuit diagram to perform a repair, check these common failure points: Unlike simpler layouts, the S-360-12 features a distinct
Inspect the output electrolytic capacitors. Look for bulging tops or leaking electrolyte. High ESR in aging capacitors breaks down the filtering capability, confusing the feedback loop. Look for bulging tops or leaking electrolyte
