Mounting in push-through technique
(thermal separation of the heatsink)
ƒ
For units in the power range 0.37 kW to 75 kW mounting
sets for thermal separation ("push-through technique") are
available.
ƒ
The protection class of the separate cooler is IP 41.
ƒ
When the servo inverters are mounted in "push-through"
technique or "cold plate“ technique, only built-on mains
filters can be used for interference suppression.
Thermal separation of the heatsink is recommended for some
applications. It significantly reduces heat generation inside
the control cabinet.
Units with the heatsink outside the control cabinet can be
supplied for such applications. The power loss is distributed
as follows:
ƒ
Approx. 65% via separated cooler (heatsink and fan),
ƒ
Approx. 35% internally in the drive.
The use of thermally separated heatsinks is particularly suit-
able for applications in which self-ventilation via the control
cabinet surface is insufficient. The "push-through technique"
special design enables air conditioners or fans with lower
ratings to be used or, in some cases, to be left out altogether.
