POWER RATINGS

Rating Continuous Duty* Heavy Duty* Medium Duty* Intermittent Duty*

Rating Definitions

Ratings are based on ISO 8665 conditions of 100kPa(29.612 in Hg) and 25 °C (77 °F) and 30% relative humidity. Propeller shaft power represents the net power available after typical gear losses and is 97% of rated power. Power rated in accordance with IMCI procedures.

Continuous Duty

Intended for continuous use in applications requiring uninterrupted service at full power. This rating is an ISO 3046 standard power rating.

Heavy Duty

Intended for continuous use in variable load applications where full power is limited to eight hours out of every ten hours of operation.
