If the generator isconnected to a battery to chargeit, its DC output voltage increases. The battery is chargedat the increased
voltage level. Performance curve @ applies to a case under a resistanceload only; and curve (iJ represents battery charging
characteristics.
NOTE: Up to the rated ouqout it is possible to take outsimultaneously the output of both AC and DC in total.

Portable, Light in Weight, Compact, andEasy toCarry
*The LC102 and LC152 employ lightweight, compact, powerful EY15D and EY2OD engines.
*All models employ a lightweight, high-efficiency,revolving field type generator.
Solid StateIgnition System
*Compared to the contact point type. this system has no contact points to wear out or replace. Therefore, mainte-
nance is reduced and constantoutput power can be maintained for alonger period of time.
*Easy to start with increased starting spark energy.
Extra Quiet Operation
*All models are equipped with alarge capacity, low-noise muffler.
*.a models are equipped with a cyclonetype air cleaner which reducesnoise and is excellent in keeping dustout.
Effective Voltage Regulation withAVR (Automatic Voltage Regulator)
*The built-in AVR automatically regulates the exciting currentto keep voltage regulation at less than
3%, thereby pro-
tecting the load(an electrical product) and prolongingits product life.
DC Output forBattery 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 anAC output. The combined AC and
DC outputsmust be
kept undr the ratedlevel.
Dual Voltages Are Available
on LC201D and LG301D
*A dual voltage type which suppliestwo AC voltagesis availablein the 2kW and
3 kU' classes.
Output VoltageWaveform Closeto SineWave
*Output voltagewaveforms are close toa sine wavewithout asurge
so that theload electrical productwill not be dam-
aged.
Resistant to Induced Load
*Excited power is obtained from the sub coilthat is wound separately from themain 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 whichare subject to sharp current fluctuations-andeasier starting of an induction motor.
100% Copper Windings
*The use of pure copper whichhas low internal resistance forwindings assures
high efficiency and long generator life.
Easy Starting with a Recoil Starter
Trouble-Free with a
Fuse or No-Fuse Breaker
LGK Type OperatingonKerosene
*Automatic fuel changing system uses gasoline to start the generator and automaticallychanges it tokerosene in nor-
mal operation.
