Features

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.

Connection Examples and PWM Signal Output Characteristics

Controller can be common-powered by the power supply for 12, 24, and 48 VDC rated voltage fans. It can also be powered by a separate supply as long as both supplies share the same ground.

・ Voltage control   Output duty cycle controlled with input voltage of 0 to 5 VDC *Ensure that the input voltage does not exceed 5.5 VDC.

Voltage control

・ External adjustment (variable resistor) control   Output duty cycle controlled with variable resistor connected to terminals

External adjustment (variable resistor) control

・ Thermistor control Automatic control of output duty cycle in response to the temperature detected with an external thermistor
