2.6. CONVERTER SIZE SELECTION

Within the specified voltage field, the SM-32 converter supplies the same rated direct
current independently of the voltage itself. The increase of the output voltage causes an
increasing in the transferred power, whereas inverters are devices with a typically constant
transferred power (the supplied current decreases with the increasing of the output voltage).
As for the choice, therefore, the calculation is based on a common unit, the direct current
of the intermediate circuit, which, as for the inverters, is not mentioned into the product
instruction manual and has therefore to be calculated. Furthermore, the confrontation
between the two foreseen functioning classes has to be homogeneous (IEC 146 class 1 and
2).
