PRIME POWER RATING
The Prime Power Rating is the maximum power available during a variable load sequence which may be run for an unlimited number of hours per year. Prime power is
available for an unlimited number of annual operating hours in variable load applications, in accordance with ISO8528-1. A 10% overload capability is available for a
period of 1 hour within a 12-hour period of operation, in accordance with ISO 3046-1.
STANDBY POWER RATING (ESP)
The Standby Power Rating is applicable for supplying emergency power for the duration of a utility power interruption. No overload, utility parallel or negotiated outage
operation capability is available at this rating. In installations served by unreliable utility sources (where outages last longer or occur more frequently), where operation is
likely to exceed 200 hours per year, the prime power rating should be applied. The Standby Power rating is only applicable for emergency and standby applications
where the generator set serves as the back up to the normal utility source.
Unless otherwise stated all ratings are based on the following reference conditions:
- Ambient temperature – 27oC
- Altitude above sea level – 150 metres
- Relative humidity – 60%
Note: In order for KTA50G7 (C1400 D5E) to meet 2g TA Luft emission norms please refer to factory for cooling system guidelines.
