Kubota J Series Diesel Generator
Kubota J Series Generators are easy to use anywhere for long period of time.
These semi-open type generators are powered by either a SUPER MINI or a SUPER 05 Series engine. The series “ease to use anywhere” design permits operation even in limited space. The larger capacity fuel tank and its exceptional fuel efficiency guarantee longer hours of continual electrical energy on a single tank of fuel.
2-Pole Single & Three Phase
Output range : Single Phase 5.5 ~ 23.5 kVA
Three Phase 8.0 ~ 23.5 kVA
The generator and the engine are direct-coupled to ensure a more reliable power supply with minimum power loss.
Transistor Automatic Voltage Regulator (AVR)
The J-Series uses a transistor AVR to ensure a stable flow of current for most any kind of jobs you can think of.
A Skewed Rotor & Damper Winding
The waveform distortion is kept to a minimum by the skewed rotor, while the damper winding protects the generator during short circuits, regulates voltage fluctuations during condensive loads, and withstands load fluctuations during condensive and non-linear loads.
Diesel engines selected to power the J series produce far less soot, HC and CO emissions thanks to Kubota's original E-TVCS combustion.
Ease of Operation
The J-series' advanced design and superior engineering minimized both space and weight. Whether it is your backyard or in your basement, it will fit neatly in most any place you wish to put it.
Front Panel Control
Key switch, voltage meter, circuit breaker, and warning lamps are all conveniently gathered on a drip proof control panel.
Large Capacity Fuel Tank
The larger capacity fuel tank enables longer periods of continuous operation on a single tank of fuel.
One- point lifting eye and special forklift openings helped enhance the series' transportability.
All gauges and filters (except for Z482 and D722's oil filter) are conveniently situated to enhance and simplify daily maintenance.
Double Element Air Filter
A double element air filter is used in the J-Series to withstand heavy-duty use, and to protect the generator from sand-caused damages.
Automatically shut the engine down in case of abnormalities in oil pressure, water temperature, and when the fanbelt breaks*.
*Fanbelt accident prevention is only applicable to generators using D1005 and V1305 engines.
Electric Shock and Entangling Preventions
Protective covers are attached on all output terminals to prevent electric shocks. The number of safety covers has also been increased to prevent entangling accidents.
