描述

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
