WebEach fan is different in the range of input voltage to fan speed. The rule of thumb is a zero voltage input will result in a minimum speed condition and an input equal to 50% of the fans nominal voltage will result in a maximum speed condition. For instance, a 24vdc fan will operate at full speed when 12vdc is applied to the program lead. WebFor instance, a positive displacement pump requires a constant torque given constant output pressure, so K 1 will be dominant (and the power proportional to the speed [40]), whereas a large fan ...
