S36012 Power Supply Circuit Diagram [extra Quality] -

Do not exceed the MOSFET’s Vds rating. With an IRFB4110 (100V), you can raise input to 50V. However, you must:

If you have an S36012 module and want to verify your version’s schematic:

Input Protection and EMI Filtering s36012 power supply circuit diagram

Check the input fuse (F1) first. If blown, check the bridge rectifier and the main switching transistors (13009/MOSFETs) for shorts. Replacing the fuse without checking these components will usually result in another immediate failure.
