AVT929 / 1 B

Despite the continuous application of power for the lowest possible power consumption, many electronic systems require forced cooling. The fans used for this work Often in turn on / off mode, which causes excessive energy consumption and excessive noise.
The layout is an intelligent controller for four fan? W. Communication with the user is possible via the LED display or the alphanumeric LCD display. The controller has very simple designs, this was achieved using a PSoC microcontroller. It controls the speed? revolutions? each with a fan - depending on the measured temperature. Is tested also? operation of each drive engine. This makes it possible to detect the rotor seizure. Exceeding the permissible temperature is signaled acoustically.

The device is particularly useful everywhere where it is necessary to use forced cooling; in computers, power supplies, etc.

Selected parameters:

• simultaneous service of four fans?
• sound signaling of exceeding the permissible temperature threshold
• Attachment of the fan after exceeding the set temperature threshold
• motor drive seizure indication
• displaying the result in LED or LCD displays
• I2C interface for communication with the parent system
• power supply - 12 Vdc
• in the set printed boards, a set of elements and documentation
