If
the generator is connected
to
a battery
to
charge it, its
DC
output voltage increases. The battery is charged at the increased
voltage level. Performance curve
@
applies
to
a
case under
a
resistance load
only;
and curve
(iJ
represents battery charging
characteristics.
NOTE:
Up
to the rated ouqout
it
is
possible to take out simultaneously the
output
of
both
AC
and

Portable, Light in Weight, Compact, and Easy to Carry
*The LC102 and LC152 employ lightweight, compact, powerful EY15D and EY2OD engines.
*All
models employ a lightweight, high-efficiency, revolving field type generator.
Solid State Ignition System
*Compared to the contact point type. this system has no contact points to wear out or replace. Therefore, mainte-
nance is reduced and constant output power can be maintained for a longer period of time.
*Easy to start with increased starting spark energy.
Extra Quiet Operation
*All
models are equipped with a large capacity, low-noise muffler.
*.a
models are equipped with a cyclone type air cleaner which reduces noise and is excellent in keeping dust out.
Effective Voltage Regulation with AVR (Automatic Voltage Regulator)
*The built-in AVR automatically regulates the exciting current to keep voltage regulation at less than
3%,
thereby pro-
tecting the load (an electrical product) and prolonging its product life.
DC Output for Battery Charging
*A DC output of 12 V 100
W
is simultaneously available with an AC output. Therefore, the generator can charge a
battery from its DC output terminal while also supplying an AC output. The combined AC and
DC
outputs must be
kept undr the rated level.
Dual Voltages Are Available
on
LC201 D and LG301 D
*A dual voltage type which supplies two AC voltages is available in the 2 kW and
3
kU' classes.
Output Voltage Waveform Close to Sine Wave
*Output voltage waveforms are close to a sine wave without a surge
so
that the load electrical product will not be dam-
aged.
Resistant to Induced Load
*Excited power is obtained from the sub coil that is wound separately from the main coil, output voltage fluctuations
are
small
as compared with load current fluctuations and constant power can be obtained. This means greater resist-
ance to loads which are subject to sharp current fluctuations-and easier starting of an induction motor.
100%
Copper Windings
*The use of pure copper which has low internal resistance for windings assures
high
efficiency and long generator life.
Easy Starting with a Recoil Starter
Trouble-Free with a
Fuse
or
No-Fuse Breaker
LGK Type Operating on Kerosene
*Automatic fuel changing system uses gasoline to start the generator and automatically changes it to kerosene in nor-
mal operation.
