S-60-12 Power - Supply Circuit Diagram

Output filtering usually consists of two 1,000 µF electrolytic capacitors to provide a stable, low-ripple 12V DC supply. Feedback & Regulation optocoupler

That wild, bumpy DC needs smoothing. And here stood the giant: the (C5, usually 100-150µF, 200V for 110V regions; or 68-82µF, 400V for universal input). On the S-60-12’s board, Manish found a chunky 100µF/400V capacitor. It stores energy between peaks, creating a flat(ish) high-voltage DC bus of about 170V (for 120V AC) or 340V (for 230V AC). s-60-12 power supply circuit diagram
