Model: REOZJB - Kohler Power

1 model : 50 REOZJB . 190--600 V Diesel Standard Features D Kohler Co. provides one-source responsibility for the generating system and accessories. Ratings Range D The generator set and its components are 60 Hz 50 Hz prototype-tested, factory-built, and production-tested. Standby: kW 49--55 40--50 D The generator set accepts rated load in one step. kVA 49--69 40--56. D The 60 Hz generator set meets NFPA 110, Level 1, Prime: kW 45--50 35--45 when equipped with the necessary accessories and kVA 45--63 38--53 installed per NFPA standards. D A standard one-year limited warranty covers all systems and components. Two-, five-, and ten-year extended warranties are also available.

2 D Alternator features: d The unique Fast-Responset II excitation system delivers excellent voltage response and short-circuit capability using a permanent magnet (PM)-excited alternator. d The brushless, rotating-field alternator has broadrange reconnectability. D Other features: d Kohler designed controllers for guaranteed system integration and remote communication. See Controllers on page 3. d The low coolant level shutdown prevents overheating (standard on radiator models only). d Integral vibration isolation eliminates the need for under-unit vibration spring isolators.

RATINGS: All three-phase units are rated at Power factor. All single-phase units are rated at Power factor.

4 Standby Ratings: The standby rating is applicable to varying loads for the duration of a Power outage. There is no overload capability for this rating. Prime Power Ratings: At varying load, the number of generator set operating hours is unlimited. A 10% overload capacity is available for one hour in twelve. Ratings are in accordance with ISO-8528-1 and ISO-3046-1. For limited running time and continuous ratings, consult the factory. Obtain technical information bulletin (TIB-101) for ratings guidelines, complete ratings definitions, and site condition derates. The generator set manufacturer reserves the right to change the design or specifications without notice and without any obligation or liability whatsoever.
