PWM (Pulse-width modulation) regulates the voltage signal between fully on and fully off, controlling the speed of a fan. The PWM function is commonly used in OEM cases. Delta also provides standard PWM through distribution channels. Delta's internal PWM signal control fans deliver a variety of advantages over external PWM controlled devices:
- Wide PWM Frequency Range Input (30Hz- 30kHz)
- Lower vibration at lower duty cycle
- Prevent spike current on fan speed control
- Better motor efficiency
- Lower fan switching noise
