FC-301 and FC-302 cooling

Filed under: GET FC-300 series — Ralf @ 8:55 AM

Intelligent heat management

Also very important is the cooling design. Some brands just blow and blow or suck and suck… the air that is… and the air is often directed through the electronic components.

Very effective, as a rather inexperienced observer might say but also here we better think again and we want to speak a little bit more about the Danfoss way of staying cool in the following lines:


Cooling can take place in various ways for different benefits:


Total separation between cooling air and electronics allows for solutions where heat is removed outside cabinets.

With VLT Automation Drive, a flanged heat sink kit is available for mounting the Drive in the back plate of an electrical cabinet.


Forced convection cooling:


A fan blows cold air through the cooling ribs of the aluminum base. The channel is easily cleaned without touching any electronics.


Cold plate cooling:


External cooling is possible through the back side of the aluminum base.

Innovative design reduces the risk of contaminants entering the Drive and the panel. Contaminants like dust which is really a killer for electronics in general but here in the Philippines very much in particular.

This is so because we are living and working here in a tropical environment which is not only hot but also humid, even more so in specific areas like for example steaming departments and such alike.

Any accumulation of dust covers would not only heat up the electronics but the humidity could turn this contamination even conductive, especially so during an intended or unintended standby mode or downtime because this would cool the unit down and some specific areas would even catalyze the development of additional condense water, so dust is a really a very potential killer, especially so here in the Philippines

This Danfoss solution though does ensure a long life of the Drives.

With the duct cooling kit excess heat can be ventilated outside the control room and even outside the whole building.

The need for additional air conditioning components and the attached energy consumptions of such components is limited.

A smart dedicated kit allows D3 and D4 enclosures to be mounted in Rittal cabinets so that cool air removes 85% of excess heat without contact to the electronics.

Despite all this features the Danfoss Automation Drive is not bulky or heavy equipment.


Small footprint:


VLT Automation Drive has a compact design. All power sizes are smaller than the predecessors like for example the just recently discontinued famous Danfoss VLT-5000 series. No dimension has increased and volumes are typically 20% smaller.

The Drives can still be mounted “side by side” with literally no (0 zero mm) clearance.


Conversion kit:


A conversion kit is available to facilitate exchange from earlier VLT Drives. The back plate has pre-drilled holes and the cabling from the VLT-5000 can be reused with the terminal adapter.


Closure for this post:


In earlier blog entries we did include already quite a variety of downloadable links to brochures, catalogues, manuals, overviews, presentations, videos, etc, etc, etc but here we decided to leave the sheets more clean in order not to spoil the message.

However, we would still highly recommend to read as well our

GET Drives Category

GET Savings Category

GET Applications Category

GET to know VFD’s Category

It is precisely there where you will find much more information to the general subject plus much more specific referrals to very much related downloads. When you prefer to view directly all the corresponding file folders you may also proceed directly to the FC-300 folder in our

GET Sky Drive Section

We certainly do hope that you enjoyed again the read and that you stay with us for more upcoming technical reading pleasure.
