FOUR FANS CONTROLLER - PRINTED PLATE
FOUR FANS CONTROLLER - PRINTED PLATE
Producer: AVT
Computer fans are suitable for cooling not only PCs but also for any electronic device. A set of four such fans can be useful in the workshop of every constructor electronics.
The system consists of four identical blocks. Each used an operational amplifier working as a comparator. It compares the voltage from a divider whose element is a thermistor with a reference voltage. If the thermistor resistance drops (the temperature rises), the voltage at the corresponding input of the comparator will drop. On its output will then be the voltage controlling the transistor switching the fan.
The device is particularly recommended in devices that emit a lot of heat
Selected parameters:
- four independent, identical blocks controlling the fans
- for fans powered from 12Vdc
- smooth regulation of the switching threshold
- power supply - 12 Vdc
- tile dimensions 100x34mm
- printed circuit board and documentation included
A version with a set of components for self-assembly is available
