ABOUT THE PRODUCT
1
・OGA-100 in the kit also has a stay, which supports rear part of the generator. It is an extra part included
in the kit to mount on GF40U-FI.
・This is OGA-100 generator kit to be mounted on GF40U-FI. The kit contains OGA-100 generator with a
mount, a drive belt, a drive pulley, ORF-200 regulate rectifier.
・OGA-100 is a 3-phase AC generator suitable for small engines.
・It applies a brushless motor to the system and generates electricity with stability.
・It is equipped with UH grade Neodymium magnets that have powerful magnetic force with high heat
resistance (180 ℃).
・ORF-200 is an open type regulate rectifier; an effective DC-DC converter type.
・Output voltage is adjustable from DC6V through DC28V. (The factory setting is DC12V)
・Maximum output: 200W (DC12V)/10 minutes. (when atmospheric temperature is 20℃.)
・Maximum current: 16A (DC12V). (when atmospheric temperature is 20℃.)
・Maximum input voltage: 100V (AC).
*The specifications are subject to alteration for improvement without notice.
*Consult us for any questions on this product and return for repair.

4. Loop the belt over the Drive pulley
and the engine pulley.
5. Insert the Generator into Urethane
bushing of the Generator support (R).
6. Attach the Generator support (F)
to the Generator mount together
with 4.5mm Spacers using M4x30
Bolt.
7. Fasten the M4x25 bolts of the Generator support (R) that you temporarily fastened earlier. Loosen
the Lock bolt of Generator support (F) and check if belt tension is adjustable by rotating the generator
body.
8. Rotate the generator body clockwise (viewing from the front of the engine) and adust the belt tension.
Press on the middle point of the belt with a finger and set deflection to around 2mm. Tighten the Lock
bolt after adjusting the belt tension.
The alignment mark is roughly here when the belt is
new.

Installation
1.Remove the pair of front bolts (M4 x 15) on the generator mount, where you intend to fit the
Generator. There bolts are unnecessary in case the Generator is fit.
2. Bolt the Generator support (R) to Mounting plate(F)
together with 15mm Spacers using M4x25 Bolts. Fasten
only temporarily. The Generator support (R) piece has
two sides. Check this closely.
3. Loosen the Lock bolt on the Generator support(F) and align the
marks as shown above in the red circle. Tension of the belt is the
loosest at this position.

③ Attach the lid with the four screws (tightening torque 0.5N-m). Do not attach the lid reverse since the
lid is asymmetric with a cutout for cables.
Adjustment method of output voltage
・Output voltage is adjustable between 6V to 28V.
《How to reset the output voltage》
① Remove the four screws on bottom of ORF-200, and take out the lid.
② Reset the voltage by turning the trimmer shown in the picture. You can increase the voltage by turning
it clockwise. Adjust the output voltage with no load without connecting output cable to any equipment
inputting double or more voltage than the output voltage you set. The input voltage does not have to be
3-phase AC when you adjust the output voltage. You can use single-phase AC or even DC. Use two of the
three input cables randomly selected when you use single-phase AC or DC for input.
Installation

CAUTION:
・Do not exceed the rated output values. The regulate rectifier can be overheated under high
atmospheric temperature even it is used within the rated values. So position it in a well-ventilated
place.
・When output of ORF-200 is connected to your equipment, put a 15A – 20A fuse in the RED cable
(DC +).
Installation
・Provide enough anti-vibration measures to mount it in an aircraft.
・Determine the position of the regulate rectifier, well ventilated, not to be exposed to radiation heat and
engine exhaust gas.
・Use four M4 screws when it is mounted.
・Connect three white input cables of ORF-200 to three output cables of the generator. There is no
polarity on each three cables.
・Output cables (RED DC +, BLACK DC -) do not have connectors. Prepare connectors that fit to your
equipment by yourself.

note 1. Use the mounting screws whose length does not exceed the thickness of your bracket +
4mm, so that the length of screws which is screwed into the generator body is less than 4mm. If
you screw into the screw body longer than 4mm, the screw will contacts the motor coil and will
cause short circuit.
