Delta Electronics Fans

Pulse-Width Modulation (PWM) Technology Fans

Delta’s PWM fans offer advanced cooling solutions that deliver superior performance with greater efficiency

Image of Delta Product Groups' Pulse-Width Modulation (PWM) Technology FansDelta has developed an advanced PWM circuit control utilizing soft switching, resulting in a smooth current signal to the fan. This thermal technology further reduces vibration and noise while continuing to provide better performance, high reliability, and cost-effective thermal cooling solutions. 

PWM regulates the voltage signal between fully on and fully off, controlling the speed of a fan. The main advantage is that power loss in the switching device is very low. When a switch is off, there is practically no current and when it is on, there is almost no voltage drop across the switch. Therefore, power loss is close to zero.

Delta carries a full line of PWM speed control fans with dimensions ranging from 36 mm x 36 mm x 28 mm up to 280 mm x 280 mm x 80 mm.

Features and Benefits
  • Advanced soft-switching control (available on certain models)
  • Flexible speed control
  • Wide PWM frequency input range (30 Hz to 30 kHz)
  • Prevents current spikes
  • Low switching noise
  • Low vibration
  • High power efficiency
