Control cabinet air conditioning/
resulting power loss
The resulting losses in the control cabinet
are, on the one hand, dependent on the
installed modules in the BT356 (static power
loss) and, on the other, on the tightening case
Power
consumption
(variable power loss). The calculation for
expected losses is as described below.
