Heavy Duty (KJ) Series
| DEPENDABLE GENERATION |
Direct Coupled
The generator and the engine are direct-coupled to ensure a more reliable power supply with minimum power loss.
Brushless Alternator
This
brushless, self-excitation type alternator is designed to be used in a
wide variety of difficult starting conditions. Its Load Acceptance
Module (LAM) enables the engine to accept larger load impacts and to
regain its rated speed more quickly. Its convertible (50/60 Hz)
electronic regulator is powered independently from the voltage
detection circuit; therefore, regulation is not affected by distortions
generated by the load.
Transistor Automatic Voltage Regulator (AVR)
All
KJ Series generators are equipped with a transistor AVR to regulate a
stable flow of current. In addition, any local condition can be matched
by the knob.
|
| EASE OF OPERATION |
Reduced Sound and Vibration
Kubota's inherent low noise design, a sound attenuated enclosure
which effectively reduced all sound including that of the muffler, and
the original TVCS combustion system substantially reduced the sound
levels. Inserting rubber pads and additional supporters in critical
areas also reduced integral vibrations.
Convenient Front Panel Control
All switches and lamps are conveniently located in the center of the front panel for maximum accessibility. |
|
|
| CAREFREE MAINTENANCE |
One Side Maintenance
Oil, fuel, water, and filters are all located on one side for easy maintenance. |
|
Automatic Air Bleeding
Air bubbles, which can rob the engine of its power, are
automatically removed from the fuel line.
Easy-to-Mount & Remove Battery Pack
The battery pack, located in the rear of the generator, can be easily removed through the back panel. |
|
|
| INCREASED SAFETY |
Automatic Shutdown Mechanism
Should any abnormality occur in oil pressure or water temperature,
this mechanism automatically stops the engine before it can be damaged.
Emergency Unit
Kubota gathered the emergency relay, timer relay, and safety relay
into one unit to save space, simplify the wiring scheme, and to improve
protection against water, dust, and vibration. Key stop and mechanical
manual emergency stop mechanisms are also included in this unit.
Protective Design
All rotating parts of the generator have been covered by a metal enclosure for maximum operator safety.
Load Center
All output terminals have been gathered on the side of the
generator rather on the front. This new location will help reduce the
cables from being tangled.
