Converts AC to high-voltage DC (roughly 310V DC for a 220V input).
The is one of the most ubiquitous industrial switching power supplies on the market. Rated for 12V DC at 30A (360 Watts) , it is the "workhorse" for 3D printers (like the Creality Ender series), CCTV systems, and amateur radio setups.
Limits the "inrush current" when you first flip the switch. s36012 power supply circuit diagram
The circuit begins with the AC input (110V/220V), which passes through:
If you are looking at an S360-12 circuit diagram to perform a repair, check these common failure points: Converts AC to high-voltage DC (roughly 310V DC
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
A combination of X/Y capacitors and a common-mode choke to prevent high-frequency noise from leaking back into your wall outlet. Limits the "inrush current" when you first flip the switch
Usually a pair of 13009 NPN power transistors. These turn the high-voltage DC into a high-frequency AC signal (usually 50kHz–100kHz).
