Speed Setting
1. Full Speed: Short Red and Yellow; fan will run at full speed.
2. Voltage Control 0-10 VDC (±0.2 V): User DC power supports 0-10 VDC. Voltage higher than 1.0 VDC: fan starts. Voltage lower than 0.5 VDC: fan stops.
3. PWM Control: PWM duty 0%-100% (±2%). Suggested amplitude: 10 VDC (±5%). Frequency: 1 kHz-10 kHz. Duty higher than 10%: fan starts. Duty lower than 5%: fan stops.
4. Potentiometer Control: Suggested 10 kΩ potentiometer. Voltage higher than 1.0 VDC: fan starts. Voltage lower than 0.5 VDC: fan stops.
Signal Feedback: The fan provides a speed output signal. Vfg and the pull-up resistor are connected by the customer. Vfg=(3.3-30)VDC, R≥1000×(Vfg)Ω. Speed calculation: n=60f/a, where n is fan speed, a is pulses per revolution, and f is signal output waveform frequency.
