■ Features
Reduces system power consumption and fan noise
For PWM fan speed control, a PWM control circuit needs to be
newly designed and congured.
By using this product, however, PWM control function fans can
be fully utilized without the need for preparing new circuits,
contributing to reducing the system power consumption and
the fan noise.
Can be common-powered by the fan power supply
The controller can be powered by the fan power supply of
rated voltage 12, 24, and 48 VDC, and no separate supply is
required.
Maximum of four fans connectable
Up to four fans with PWM control function can be connected
and controlled.

*** Variable resistor and thermistor are not supplied with the controller and need to be prepared separately.
Be noted that if applied input voltage or frequency is out of range of the connected fan, how the fan speed responds to the PWM duty cycle may be altered.
