PWM Controller ■ 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. PCB type ■ Specifications Model no.

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. ■ Front View (component names) • PCB type Temperature selector switch 温度設定スイッチ Ground terminal グラウンド端子 Power supply input terminal 電源入力端子 Thermistor connection terminals サーミスタ接続端子 （サーミスタコントロールのみ） only) (for thermistor control model Control voltage ground or コントロール電圧グラウンド， variable resistor または可変抵抗接続端子 connection terminal Control voltage コントロール電圧入力端子 input terminal Variable resistor 可変抵抗接続端子 connection terminals Control function selector switch 機能切替スイッチ PWM output voltage VOH OH 切替スイ

■ 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. • Box type DC power supply Control Voltage Output Duty Cycle Characteristics Output duty cycle Control voltage Internal adjustment (variable resistor) control Output duty cycle controlled with the adjustment knob....
