A 2-wire fan is controlled by adjusting either the dc voltage or pulse
width in low-frequency PWM. However, with only two wires, a tach signal
is not readily available. This means that there is no indication as to
how fast the fan is running—or indeed, if it is running at all. This
form of speed control is open-loop.
Su tam nejaki specialni diablici, na ktorych si treba dat pozor?
Dakujem,
