ANALOG FAN SWITCH REGULATOR - SELF-ASSEMBLY KIT
Producer: AVT
The system has been designed for active cooling of a high power amplifier and allows for the regulation of the rotation of four fans depending on the temperature. The popular temperature transistor is BD139. Accuracy is not important, and the use of this type of transistor reduces the cost of the entire system. In addition, the housing of this transistor can be easily screwed to the heat sink, ensuring good thermal contact. The rotation control consists in a smooth change of the output voltage, so it does not generate any additional disturbances, which makes it perfectly suitable for power amplifiers. With quiet listening, when the power loss is small and the cold radiator - the fans are not audible.
The set includes a printed circuit board, a set of elements and documentation.
