Air purifier has become an essential appliance in every home and especially during the hazy season, it sells like a hot cake. I bought this back in 4 years ago when the haze problem became intolerable in Malaysia. This is a basic air filter with HEPA filtration with Plasmacluster Ion feature from Sharp. I took this opportunity to tear it down when it requires thorough cleaning since the day I bought it. Let's get our curious mind going and look what's inside.

Basically there are 3 sections on the controller board.
Left section - Front panel controller circuit. Middle section - AC switching circuit, Right section - Power supply circuit |

Hi, did you find out what voltages are carried on the 2 pin connector to the plasmacluster unit? Is it just 12V and ground to power the unit or is it pulsed in any way?
ReplyDeleteI am wondering too. Is it DC or AC?
