Better Generating Performance
SDG series generators are
coupled to low transient
reactance alternator and
reinforced damper coil. This
increases the
negative-phase-sequence
current 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.
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.
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.
Low Noise Level
Blowby Gas
(
SDG13~100,125S-F,150S-F
)
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.
Clean Engine
Parallel Operation
(
SDG125,150S/AS
)
High Accurate Parallel Operation System
(
CCR cross current prevention device
)
is
provided as a standard equipment.
Combined with an accurate
AVR
(
automatic voltage regulator
)
, it is
possible to perform parallel operation
manually.
Continuous Operation available for a
long time
A large capacity fuel tank
and low fuel consumption
engine have made the
generators run continuously
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
(
SDG13~150
)
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 bled automatically.
As for both SDG125S/150S/150AS, it is possible to
automatically bleed air by pushing the push button provided
at the operation panel.
