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 | 580 | 556.8 | 696 |
| Standby Power | 650 | 624 | 780 |
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.
