Standard Features

■

Heavy duty, 4-cycle, direct injection, turbocharged, air to air intercooled diesel engine provides maximum

reliability.

■

Brushless alternator reduces service and maintenance requirements and meets temperature rise standards for Class F insulation systems.

■

Open delta alternator design provides virtually unlimited excitation for maximum motor starting capability.

■

Automatic voltage regulator (AVR) provides precise regulation.

■

Electronic governor system maintains frequency to ±0.25%.

■

Full load acceptance of standby nameplate rating in one step (NFPA 110, para 5-13.2.6).

■

Sound attenuated, weather resistant, steel housing

provides operation at 72 dB(A) at 23 feet. Fully lockable enclosure allows safe unattended operation.

■

Internal fuel tank with direct reading fuel gauges are standard.

■

Fuel/water separator removes condensation from fuel for extended engine life.

■

Seven stage powder coat paint provides durability and weather protection.

■

Complete engine analog instrumentation includes DC ammeter, oil pressure gauge, water temp. gauge, fuel level gauge, tachometer/hour meter, manual engine speed control, and emergency shutdown monitors.

Complete generator analog instrumentation includes voltage regulator control, ammeter phase selector switch, voltmeter phase selector switch, AC voltmeter, AC ammeter, frequency meter, panel light, and circuit breaker.

Automatic safety shutdown system monitors the water temperature, engine oil pressure, overspeed, and overcrank. Warning lights indicate abnormal conditions.

Low coolant level shutdown system provides protection from critically low coolant levels. Includes control panel warning light.

Auto start/stop control allows generator to start automatically in the event of a commercial power failure.

Complete power panel. Fully covered; three-phase terminals and single phase receptacles allow fast and convenient hookup for most applications including temporary power boxes, tools and lighting equipment. All are NEMA standard.

Emergency stop switch

EPA emissions certified - Tier 3 emissions compliant.
