摘要： Fan controller (1) for a modular power supply having a fan (13). An output (8) is provided for transmitting control signals to the fan (13) for controlling fan speed. A plurality of sensor modules (20) are associated with a respective module (11,6,7) of the modular power supply. Each sensor module (20) includes a temperature detecting circuit comprising a sensor for sensing temperature variations in the respective module (11,6,7), a fan control circuit (30) galvanically isolated from the temperature detecting circuit for outputting a control signal to the output (8) for controlling the fan (13), and an optocoupler (10,9) for transferring an output signal from the temperature detecting circuit (20) to the fan control circuit (30) for generating the control signal.
