What Ingress Protection (IP) is right for my installation?

When selecting your Danfoss drive ensure you select the right Ingress Protection (IP) for the longevity of your VSD. 

  • Cabinet installation is IP20 and IP21 
  • Standard plant room wall installation is IP54 and IP55
  • Extreme environment installation IP66 

What is a EMC Filter?

EMC filters are differential-mode low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal. This reduces the motor insulation stress and bearing currents.

What is a variable speed drive?

Variable speed drives (VSDs), also called adjustable speed drives (ASDs), are devices that can vary the speed of a normally fixed speed motor. In HVAC systems, they are used primarily to control fans in variable air volume systems instead of other devices such as inlet vanes and discharge dampers.
