简介
The power supply is what transforms the alternating current electricity from a wall outlet into a lower voltage direct current that is usable by the projector. There are many sensitive electronics in a power supply, and a power surge or other electrical issue can fry capacitors and other delicate components, breaking the power supply and preventing the projector from turning on.
The power supply in this projector has an enclosure which the speaker and main fan are mounted on, and the base of the enclosure with the attached power supply can be removed and replaced.
