Derating of the output current due to line voltage and ambient temperature

INFORMATION

Interpolate linearly for voltages between 400 V and 500 V.

The following table shows the values for derating as a function of the line voltage Vline and ambient temperature T > 40 °C:

ICont

Continuous line current

Inominal

Nominal line current

T

Ambient temperature

Regenerative power supply

Continuous line current ICont

Vline: 3 × 400 V

Vline: 3 x 500 V

Icont/Inom = 100% - (T - 40 °C) × 2.05%

Icont/Inom = 80% - (T - 40 °C) × 1.9%
