Pulse-Width Modulation - PWM
Delta Pulse Width Modulation PWM fans offer full lineup of speed control. PWM fans have advanced cooling solutions, deliver best performance and greater effciency. PWM 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
