The voltage curve shown in the left indi-
cates the characteristic of DC output when
charging a battery.
The voltage may be decreased by 20%
when the resistance load is applied.
NOTE: It is possible to use both DC and
AC outputs simultaneously up
to the rated output in total.

4. CONSTRUCTION AND FUNCTION
4-1 CONSTRUCTION
4-2 FUNCTION
4-2-1 STATOR
The stator consists of a laminated silicon steel
sheet core, a main coil and a condenser coil which
are wound in the core slots.
The condenser coil excites the rotor field coil which
generates AC voltage in the main coil.

4-2-2 CONDENSER
Two condensers are installed in the control box and
are connected to the condenser coil of the stator.
These condensers and condenser coil regulate the
output voltage.
4-2-3 ROTOR
The rotor consists of a laminated silicon steel sheet
core and a field coil which is wound over the core.
DC current in the field coil magnetizes the steel
sheet core. Two permanent magnets are provided
for the primary exciting action.
A diode rectifier and surge absorber is mounted inside of the insulator.

4-2-4 FUSE
The 10 ampere DC fuse mounted on the control
panel protects whole DC circuit from getting dam-
age by overload or short circuit.
4-2-5 NO-FUSE BREAKER
The no-fuse breaker protects the generator from getting damage by overloading or short circuit in the
appliance. The table below shows the capacity of no-fuse breaker by each spec. and their object of pro-
tection.
MODEL SPECIFICATION NO-FUSE BREAKER OBJECT of PROTECTION
RGD3300H 120/240 V 14 A × 2 Total output amperage
RGD5000H 120/240 V 20 A × 2 Total output amperage
30 A Output from 30 A receptacle
