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. Operating voltage range [VDC] 7 to 60 Operating temperature [℃] VOH (high level voltage): 3.3 or 5 VDC (selectable)，Frequency: 25 kHz Up to 4 fans Voltage control, Internal adjustment (variable resistor) control, Control functions External adjustment (variable resistor) control*3, Thermistor control*2, 3 Voltage control Mounting method DIN rail mounting or screw mounting Screw mounting Case: Plastics *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. ■ Front View (component names) PCB Type BOX Type Ground terminal Power supply input terminal Thermistor connection terminals Control voltage ground or variable resistor connection terminal Control voltage input terminal Temperature selector switch (for thermistor control model only) Variable resistor connection terminals Control function selector switch PWM output voltage VOH selector switch Adjustment knob Input terminals PWM signal output terminals PWM signal output terminals
