Generator Set Ratings

Voltage configuration is not available from the factory. Field- adjustable by an authorized service technician.

RATINGS: All three-phase units are rated at 0.8 power factor. All single- phase units are rated at a 1.0 power factor. 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. Ratings are in accordance with ISO-8528-1 and ISO-3046-1. Obtain technical information bulletin (TIB-101) for rating guidelines, complete rating 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. For dual fuel engines, use the natural gas ratings for both the primary and secondary fuels.

Alternator Specifications

• Total harmonic distortion (THD) from no load to full load with a linear load is less than 3.2%.
• NEMA MG1, IEEE, and ANSI standards compliance for temperature rise and motor starting.
• Sustained short-circuit current of up to 300% of the rated current for up to 10 seconds.
• Sustained short-circuit current enabling downstream circuit breakers to trip without collapsing the alternator field.
• Self-ventilated and drip-proof construction.
• Superior voltage waveform from a two-thirds pitch stator and skewed rotor.
• Windings are vacuum-impregnated with epoxy varnish for dependability and long life.

Controllers

APM402 Controller
Provides advanced control, system monitoring, and system diagnostics for optimum performance and compatibility.

• Digital display and menu control provide easy local data access
• Measurements are selectable in metric or English units
• Remote communication thru a PC via network or serial configuration
• The controller supports Modbus protocol
• Integrated hybrid voltage regulator with ±0.5% regulation
• Built-in alternator thermal overload protection
• NFPA 110 Level 1 capability
• Refer to G6-161 for additional controller features and accessories.

Sound Enclosure

• Sound level (8-point logarithmic average) at 7 m (23 ft.) with full load: 69 dB(A).

• Sound level compared to competitor ratings with no load: 68 dB(A).*

• The sound attenuating enclosure uses acoustic insulation that meets UL 94 HF1 flammability classification and repels moisture absorption.
  Vertical air inlet and outlet discharge with 90-degree bends to redirect air and reduce noise.
