MULTI-PAK TM

Diesel Powered Generator

Heavy Duty EngineHeavy duty, 4-cycle, diesel engine; naturally aspirated, oil cooled.Electronic speed control governor.Meets EPA emissions standards for mobile off-highway.

AlternatorBrushless, 4-pole, synchronous, 4 lead design.Class H insulation system conforms to NEMA MG1-22, BS5000,CSA-C22-2, IEC-34-1 standards for temperature rise.Sustained short-circuit capability allowing downstream coordinationbreakers to trip without collapsing the generator field.

Drip-proof, self-venting, amortisseur windings.

Epoxy impregnated windings with tropical insulation for increasedenvironmental protection and long life.

Exceptional waveshape and voltage balance; 2/3 pitch winding tominimize harmonic distortion.

Electronic Voltage Regulator

Rating Guidelines

STANDBY POWER: Rating corresponds to ISO Standard Fuel Stop Power. It isapplicable for supplying standby electrical power at variable load in areas with wellestablished electrical networks in the event of normal utility power failure. Nooverload capability is available for this rating.

PRIME POWER: Rating corresponds to ISO Standard Power for continuousoperation. It is applicable for supplying electrical power at variable load for anunlimited number of hours instead of commercially purchased power. A 10%overload capability is available for this rating.

SINGLE PHASE OUTPUT: Broad range alternators can supply single phase out-put up to 2/3 set rated 3-phase kW at 1.0 P.F. Refer to Amperage chart.
