3 Installation

The power loss (W) is obtained by multiplying this power loss factor by the
load current (e.g. 65A)
that flows at max. load voltage (e.g. 110V) through the load resistor

Power loss = 65(A) x power loss factor

Power loss = 65(A) x 7.8 = 507W

Example of the
SIC heating
elements

SIC heating elements

SIC heating element data: new: 60V/70A, old 120V/35A; P = 4200W

h Determine the maximum load voltage actually taken (e.g. 60V) 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., 6.6.

The power loss (W) is obtained by multiplying this power loss factor by the
load current (e.g. 70A)
that flows at max. load voltage (e.g. 60V) through the new SIC heating element

Power loss = 70(A) x power loss factor

Power loss =70(A) x 6.6 = 462W

Wall
fixing

h Use 4 bolts to fix the converter vertically on a heat resistant switch cabinet

back panel.

IPC type: 709050/91-12-400-120-070/252
Load voltage = 120V
Load current = 70A
Voltage supply to the power section = 400V
P control, P = 4200W

The temperature of the air drawn in through the ventilation grille
must not exceed 35° C. Ensure that the inlet air of the built-in
ventilator can escape freely at the top and bottom!
