that flows at max. load voltage (e.g. 140V) through the load resistor
Power loss = 90(A) x power loss factor
Power loss = 90(A) x 8.5 = 765W
Example of the
SIC heating
elements
SIC heating elements
SIC heating element data: new: 70V/90A, old 140V/45A; P = 6300W
h Determine the maximum load voltage actually (e.g. 70V) of the new SIC
heating element and find the point intersecting with the curve for the
voltage supply in the power section. The Y axis shows the attendant power
loss factor of, e.g., 6.8.
The power loss (W) is obtained by multiplying this power loss factor by the
load current (e.g. 90A)
that flows at max. load voltage (e.g. 70V) through the new SIC heating element
Power loss = 90(A) x power loss factor
Power loss = 90(A) x 6.8 = 612W
Wall
fixing
h Use 4 hexagonal M6 bolts (at least quality 8.8) to fix the converter vertically
on a heat-resistant switch cabinet back panel.
IPC type: 709050/92-12-400-150-100/252
Load voltage = 150V
Load current = 100A
Voltage supply to the power section = 400V
P control, P = 6300W

The temperature of the air drawn in through the ventilation grille
must not exceed 35° C. Ensure that the inlet air for the built-in
ventilators can be taken in from below and escape at the top
without obstruction!
