Power Ratings
kWm = mechanical shaft power · kWe = electrical output · kVA = kWe ÷ 0.8 pf · kWe estimated — see note below
50 Hz1500 RPM
| kWm | kWe | kVA | |
|---|---|---|---|
| Prime Power | 695 | 667.2 | 834 |
| Standby Power | 800 | 768 | 960 |
Note: The manufacturer does not publish a separate kWe rating for this engine. kWe values shown are estimated from the rated mechanical output (kWm) using a conservative 90% alternator efficiency factor.
