| kWm | kWe | kVA | |
|---|---|---|---|
| Prime Power | 26.7 | 24 | 30 |
| Standby Power | 30 | 27 | 33.8 |
60 Hz1800 RPM
| kWm | kWe | kVA | |
|---|---|---|---|
| Prime Power | 33.3 | 30 | 37.5 |
| Standby Power | 36.7 | 33 | 41.3 |
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.
