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.
