    NORDAC ON / ON+ (SK 3xxP) – Manual with installation instructions 8.2.4 Reduced output current due to low voltage The frequency inverters are thermally designed with regard to the rated output currents. For lower low voltages larger currents cannot be used in order to keep the output power constant. For mains voltages above 400 V the permissible output current is reduced inversely proportional to the mains voltage in order to compensate for switching losses.
