MQP240
Diesel Generator
Prime Rating — 240 kW (300 kVA)
Standby Rating — 260 kW (330 kVA)
3-Phase, 60 Hertz, 0.8 PF
STANDARD FEATURES
Heavy duty, turbocharged, direct injection 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 with idle switch 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 73 dB(A) at 23 feet. Fully lockable
enclosure allows safe unattended operation.
Fuel/water separator removes condensation from fuel for
extended engine life.
Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, fuel gauge, water temp. gauge,
tachometer/hour meter, preheat indicator, manual engine
speed control, emergency shutdown monitors, and emergency
stop button.
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.
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.
Two stage air filter
E-Coat primer with polyurethane enamel finish coat.
Low coolant level shutdown system provides protection
from critically low coolant levels. Includes control panel
warning light.
