Post Para agregar mas Refrigeracion al MAX PRO I? Reply with quote
Estoy instalando el Max Pro I en una caja de metal, pero quiero agragarle un cooler o pequeño extrator de aire, al conectarlo al la fuente de poder se contamina la señal de audio con el ruido del dispositivo.

Como Hago para filtrar el ruido del extrator..?

Saludos!!! y Gracias

The final is cooled by the metal enclosure so its not really necesarry
to use a fan. If you do want to use a fan, you might have problems
with the noise, generated by the fan. There are a few hints for those
who want to use fan:

- Move it a bit away from the board, especially the VCO.
- Power it from a separate power supply or at least use LC or RC
filter to clean the power going to the fan. This can be some ceramic
100nF capacitors and some higher value electrolytics with 1uH rfc.
You can also clean the power to the fan with 7812 plus some LC
filtering. Also move cables going to the fan away from the transmitter
as they themselves radiate interference.

normalmente la mayoria de los ventiladore para refrigeracion de pequeños aparatos suelen llevar escovillas por eso seguramente es el ruido que se escucha un pequeño chispeo que a gran velociad se convierte en un sonido contante y molesto,,,,,,yo que tu intentaria buscarme un ventilador sin escovillas y asunto resuelto,,o bien poner una pequeña fuente aparte para el ventilador , que seria tambien una solusion ya que esos ventiladores no consumen casi nada y en la misma caja te puede caber perfectamente,,,y otra seria ponerle unos filtros pero no sabria calcularte de cuanto serian los condensadores,,,,,,,,,,
por cierto eres delos pocos alos cuales puedo entender aqui en este foro ,,,almenos hay uno,,,saludossssss desde españa
