(1) Steady state rated current in the following conditions:
- 5 kHz switching frequency.
- Surrounding air temperature as specified in the table. For higher temperatures, limited to 50 ºC (122 °F), the output current must be derated by 2 %
for each ºC above the maximum specified temperature.
- Air relative humidity: 5 % to 90 % non-condensing.
- Altitude: 1000 m (3.300 ft). Above 1000 m (3.300 ft) up to 4000 m (13.200 ft) the output current must be derated by 1 % for each 100 m (330 ft)
above 1000 m (3.300 ft).
- Ambient with pollution degree 2 (according to EN50178 and UL508C).
(2) The motor outputs are only for guiding purposes for WEG motor 460 V, 4 poles. The proper sizing must be done according to the rated current of the
motors used.
(3) The dissipated powers are valid for rated operating conditions, that is, for rated output current and switching frequency.
(4) The dissipated powers for flange mounting correspond to the total losses of the inverter minus the losses on the power modules (IGBT and rectifier).
