Speed in RPM
(1) Ambient temperature 40°
C
Wind speed 10 m/s cooling the housing
Winding temperature rise < 100°
C
Stator housing in contact with the ambient air or integral on all its peripheral area with a metallic armature in contact with the ambient air
Stator housing secured on a metallic frame getting an area equal to twice the cross section of the housing
(2) Operation in sine wave mode with unity power factor
(3) Line to line voltage. Voltage level may be adapted according to the application; please contact us
(4) Line to line voltage, alternator at no load, rated speed and at 20°
C
(5) For current at rated power
(6) For curents lower than 53 Amps, one cable
For curents over 53 Amps, four single wires output (highlighted in the table)
