Reduces system power consumption and fan noise

For PWM fan speed control, a PWM control circuit needs to be

newly designed and configured.

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.

(1) When output terminals are turned on. (2) Control functions are mutually exclusive for Box type.

(3) 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.
