Heavy duty, 4-cycle, direct injection, diesel engine provides
maximum reliability.
Automatic start/stop control — automatically starts the
generator set during a commercial power failure when used
in conjunction with a transfer switch.
Brushless alternator reduces service and maintenance
requirements and meets temperature rise standards for Class
H insulation systems.
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.
Open delta excitation design provides virtually unlimited
excitation for maximum motor starting capability.
Automatic voltage regulator (AVR) provides precise regulation.
Automatic safety shutdown system monitors the water
temperature, engine oil pressure, overspeed and overcrank.
Warning lights indicate abnormal conditions.
Electronic Governor Control — maintains frequency to within
0.25% from no load to full load.
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. The GFCI receptacles
are NEMA 5-20, and the auxilillary outputs use CS6369 twist-
lock receptacles.
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 65 dB(A) at 23 feet. Fully lockable enclosure
allows safe unattended operation.
Internal fuel tank with direct reading of fuel gauge.
Simultaneous single and three phase power.
Seven stage powder coat paint system provides durability
and weather protection.
Voltage selector switch offers the operator a wide range of
voltages that are manually selectable. Fine tuning of the
output voltage can be accomplished by adjusting the voltage
regulator control knob to obtain the desired voltage.
Fuel/water separator removes condensation from fuel for
extended engine life. Panel mounted alarm light included.
Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge, fuel level
gauge, tachometer/hour meter, preheat indicator, emergency
shutdown monitors.
EPA emissions certified - Interim Tier 4 emissions compliant.
