Benefits
The LSA R and LSA H are enclosed alternators (IP 55).
- LSA R cooling is performed by an air/air exchanger (cooling index: IC 6.A1.A1 in accordance with IEC 60034-6 standard).
- LSA H, cooling is performed by an air/water exchanger (cooling index: IC 8.A1.W7 in accordance with IEC 60034-6 standard).
These alternators can be ATEX (Explosive Atmosphere) certified in accordance with EEXem II T3 protection.
