Table 3-2 400V drive ratings (380V to 480V ±10%)
The SPMD1404 can deliver 350A continuously only if the ambient is 35
°
C or lower and it is docked to the SPMC. Under all other circumstances the current rating is 335A.
The above current ratings are given for max 40°C (104°F), and 3.0 kHz switching. Derating is required for higher switching frequencies, ambient
temperature >40°C (104°F) and high altitude. For further information, refer to both the Unidrive SP and SPM User Guides.
