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 @ represents battery charging
characteristics.
NOTE: Up to the rated output it is possible to take out simultaneously the output of both AC and DC in total.

3. FEATURES
1. Lightweight, Compact
The Robin engine and revolving field generator designs provide added output poxer per weight and economical operation.
7. Centralized Control
The witches. meters. and receptacles
are
located together on a large-sized control box. and all operating controls are
located on top of the engine for eas)- generator operation.
3. Large IO-Liter Gas Tank
*IO-liter (2.6 LT.S. gal.) fuel tank is provided for nine hours of operation for Model RGSl8O and eight hours ior 1lodel
RGX240 (at the 5OHz rated output power,).
*The tank has a
fuel
gauge which shows the remaining amount of fuel m the tank.
4. Solid State Ignition System
*Unlike the breaker point svstem. the solid state rgnition s>-stem has no contact points so that maintenance
dur
to
point wear is unnecessary- and constant output power can be maintained ior long periods.
*Increased spark eners makes starting cask-.
5.
Extra-Quiet Operation
*X11 models are equipped with a large-sized. low-noise muifler.
*All models have a cl-clone type air cleaner of a low-noise, dustproof type.
6. Small Voltage Fluctuations by XVR (Automatic Voltage Regulator)
The automatic voltage regulator wtomatisally adjusts
th2
exciting current to hold voltage regulation down to
less
than 35. This helps prolong product life without dama-@ng the electric devices.
7.
DC Output for Battery Charging (RGX240. RGX240D)
The generaror can generate a DC output ( 13.. lOO\V) whtle generating an XC output so that batteries <an be charged
during XC operation. In this case, make sure that the total XC and DC output does not exceed the rated output.
8. Dual Voltages are Available on RGX240D.
* -4 du-al voltage type lvhich supplies AC voltage is available.
9. Output Voltage Waveform Close to Sine Wave
The output voltage a-aveform is close to a sine wave and is free of surges so that the load w-ill not be damaged
10. Resistant to Inductive Load
Exiting poner is obtained tram the sub coil which is wound apart irom the main
coil. This means less output roltage
fluctuations against load variation. and thus a stead!- level ofpawer. This feature is efiective partrcularly for induction
motors. for example. kvhich are subject to sharp current variation.
11. 1005 Copper Windings
The windings are made onI>- of copper having lon internal resistance. This feature also helps improve generator effimien+ and prolong generator
lif2.
-6-
12. Easy Starting with Recoil Starter
13. Circuit Breaker for Troublefree Operation
14. Ruggedly Built Frame
The box type frame is so ruggedly built that two or more generators can be stacked. Another convenient feature of
the Robin generators.
15. A Caster Type is Optionally Available.

The stator consists of a laminated silicon steel sheet core,
copper wire which winds the core, and lead wires which de-
liver the power. The copper wire is wound into the main
coil. sub (.ausiliary) coil, and DC coil. XC output power
is taken from the main coil. and DC output power from
the DC coil. (DC coil is installed on Models RGX240 .md
RGXIOD only.) The outside diameters and laminated core
thickness of various models are as show below.

5-2-2 ROTOR
The rotor consists of a laminated silicon steel sheet cover
with a iield coil wound arcund it and cooling fans and slip
rings at both ends of the shaft. The field coil leads are connected to the slip rings and direct current (DC) to the field
coil turns the rotor and magnet. The cooling fans cool the
generator by drawing cooling air from the slip rings and dis-
charging it through the fans.

An exciting current is supplied from the AVR to the rotor.
The brushes are made of carbon, and the brush-holders of
plastic. It is necessary to keep the contact pressure between
the brushes and slip rings within specitic limits. Thus. care
must be taken about brush length.

5-2-6 CIRCUIT BREAKERS
Models RGX180 and RGX240 have a pushbutton circuit
breaker and Model RGX240D two pushbutton circuit 1
breakers. Nomrallp, the pushbutton circuit breaker is closed
with the button pushed into the panel to keep the circuit :
live. If an overcurrent runs. the button comes out to break
the circuit. The circuit can be closed again by simply pushing the button in. The circuit breaker is a thermo-sensitive i
type so. if the temperature inside the circuit breaker is still
high immediately after the circuit has opened, the button
may not be able to be pushed in to the ON position. or ma>-

come back out again at once. In that case, wait a while until
the inside temperature falls. and then push the button in.

5-2-7 FUSE
The fuse prevents DC output overcurrent and short<ircuir overcurrent. Ii the generator is operated at a level exceeding the
maximum current. it can cause insulation deterioration. ‘curninp. electric shock. and electric leakage. The fuse protects the
generator from these troubles. Fuse capxiry: 10.1
5-2-8 RECEPTACLE and AC PLUGS
These are
used
for raking XC output power from the generator. A total of rhree kinds of receptacles, each var)-ing in rated
voltage and current from another, are used. As man; XC plugs as the receptacles. each matching the corresponding recep-
tacle. are provided. Table 5-4 shows the rated current for each receptacle. Be careful not to use the receptacles and XC
plugs beyond the specified limits to prevent burning.

fmgers will not go in.
5-2-12 RUBBER MOUNTS (RUBBER VIBRATION
ISOLATORS)
Rubber pads for controlling generator vibration and dislocation. These are made of the most suitable rubber material
to optimum shape and hardness.
Models RGX180. RGX240. and RGXI4OD in particular
use diagonal support rubbers to reduce vibration.
