9.3.3 Derating of the Output Current Depending on the Pulse Frequency
In case of higher pulse frequency, the current is reduced insofar that the pow‐
er dissipation in power section remains more or less constant. The figure be‐
low shows the current reduction based on the pulse frequency for the differ‐
ent frequency converters.

● with 0K40...7K50, the current does not need derating
● with 11K0...18K5 at 8.0 kHz, in 0.1 kHz steps
● with 22K0 and 37K0 at 6.0 kHz, in 0.1 kHz steps
● with 30K0 at 4.0 kHz, in 0.1 kHz steps
● with 45K0...90K0 at 2.0 kHz, in 0.1 kHz steps
