Danfoss VLT AutomationDrive FC 361 Series

3.5 Back-channel Cooling Overview
A unique back-channel duct passes cooling air over the heat sinks with minimal air passing through the electronics area.
There is an IP54/Type 12 seal between the back-channel cooling duct and the electronics area of the VLT
®
drive. This back-
channel cooling allows 90% of the heat losses to be exhausted directly outside the enclosure. This design improves
reliability and prolongs component life by dramatically reducing interior temperatures and contamination of the electronic
components. Dierent back-channel cooling kits are available to redirect the airow based on individual needs.
