- Input connector (J1): Likely a 4-pin circular MIL-SPEC connector. Pins will be labeled (e.g., +28V, RTN, Chassis GND).
- Transient Voltage Suppression (TVS): A bidirectional TVS diode (e.g., 1.5KE36CA) protects against voltage spikes.
- Input Filter: A common-mode choke followed by bulk capacitors (100-470µF, 50V).
- Reverse Polarity Protection: A P-Channel MOSFET or a series Schottky diode.
