This is an AC power control and filter PCBA for mains-side power processing in high-power electronic equipment. The board combines AC input conditioning, filtering, protection-related circuitry, and relay-based power switching within a single assembly. Its layout includes dedicated power sections, wide conductive paths, and irregular PCB cutouts to meet the electrical and mechanical needs of the installed components.
The power filter board carries a UU9.8-10mH magnetic component, large film capacitors, NTC-related circuitry, surge-suppression components, electrolytic capacitors, and a power relay together with supporting control electronics. These components form the AC input filtering and power-control sections. They condition the incoming supply and switch connected power paths according to the equipment design. Exact input voltage, relay rating, current capacity, and protection specifications depend on the final electrical design and cannot be determined from the board alone.
