High Generating Performance
capability and minimizes the output waveform distortion. Therefore, they are suitable for wide range of non-linear load such as inverter, thyrister, computer
control, discharge lighting, precision instruments and instrumental device.
Operating noise has been minimized with low noise engines, equipped with highly attenuated muffler and special exhaust system design. All SDG models
(excluding SDG100S) are adopted panel structure to minimize structural clearance and reduce internal space. Combined inlet duct design further reduces the
overall noise level. Exhaust muffler system is mounted on special design support structure to reduce vibration.
The generators have been newly designed to circulate the blowby gas inside the machine (PCV system). They are driven by such environmental friendly engine to
keep the generator outside as well as the inside from being stained.
Dual Voltage Models
By changing over the short connecting plate in the control panel, the three phase output voltage can be switched to 200/220V from 400(380)/440V and vice
versa. When starting engine, the indication lamp at the operation panel goes on to display the operating voltage immediately.
Continuous Operation available for a long time
Also for SDG13S~300S three-way selection valve is provided as a standard equipment to be easily connected to an additional outside fuel tank. One way
selection method by one selection lever avoids wrong operation when changing over suction side to return side and vice versa.
Automatic Air Bleeding System
Automatic Air Bleeding Device is equipped to automatically bleed air from fuel line system. This eliminates the need to prime the fuel system again should
the generator be shutdown due to running out of fuel. Simply top up the fuel and turn the key switch to operation position, air in the fuel line system is
As for both SDG125S/150S/150AS, it is possible to automatically bleed air by pushing the push button provided at the operation panel.
High Accurate Parallel Operation System (CCR cross current prevention device) is provided as standard equipment. Combined with an accurate AVR (automatic
voltage regulator), it is possible to perform parallel operation manually.
Maintenance with Great Ease
Daily inspection such as engine oil and coolant level can be done by opening the right side door. For SDG45 & 60, one battery of two mounted batteries has
been eliminated, thus dedicated to reducing industrial waste and maintenance cost.
Mounting and Demounting Fuel Tank
Mounting and demounting fuel tank has been made easier by making the bottom floor entirely flat. It is easy to clean the interior by removing the fuel tank.
continuously performed on welded portions.
Inspection and Cleaning Radiator
Flat Frame (SDG13~300, excluding 60AS/100S/150AS)
Engine Starting Efficiency
For SDG13~220, engine preheating system consists of quick heating glow plug to easily start up engine in low temperature conditions.
SDG220~500 are driven by high start-up engine which exercises great power for earth auger and vibro-hammer operations requiring instant electric flow.
Start-up characteristics have been more improved for electric motor start-up as well as turbo charger and governor improved.
Electronic Governor (SDG13~45, 100S-F~150S-F, 220, 400, 500)
Stable engine speed can be secured because engine speed is made easier to be adjusted.
It is possible to select frequency and make fine adjustment of engine speed only by moving up and down “Switch for fine adjustment of engine speed”. It is
also possible easily to perform” Idling Operation” with the slowdown switch.
Control devices for generator and electrical appliances for engine are concentrated inside the control panel for better maintenance.
