SE900 Static Exciter Module
The SE900 static exciter module is an add on device
designed for use with the UVR and XR series universal
voltage regulator. The primary purpose of the SE900 is
to increase the maximum output amperage from a UVR
or XR series voltage regulator from 5adc to 100adc
which allows the regulator to be used as high amperage
static exciter or phase control.
Specifications:
Input Voltage 120/240vac
Maximum Output Voltage 105vdc
Maximum Forcing Amperage 150adc
Maximum Rated Output Amperage 100adc
HZ N/A
Physical Size 10 x 10 x 6in
Total Weight 6lbs
Firing Modules UVR or XR Series Regulator

Installation Instructions:
1. Connect the SE900 up to the voltage regulator as shown below.
2. Turn run/idle switch to the open position (idle)
3. Turn the internal voltage adjustment and stability adjustment on the
voltage regulator fully counter clockwise. (10 to 25 turns or until you
hear a clicking sound).
4. Check slip rings and brushes for good condition before starting up the
generator.
5. Start the prime mover and bring up to design speed.
6. Turn the run/idle switch to the closed position (run).
7. Set up the voltage regulator as per the instructions for the regulator.
Fuse the AC1 and AC2 with a fast blow fuse rated at full load amperage
of the exciter field. Do not fuse above 100 amps! Only use fuses rated
for voltages above 240vac!

Troubleshooting and bench check procedures:
1. Connect up test wiring as shown below and insulate the gray and
white leads coming from the SE900.
2. Input 120vac into the SE900 (the light should be off).
3. Connect the red wire thru a 1000 ohm, half watt resistor to terminal
AC1 on the SE900. (the light should come on)
4. Disconnect the red wire from terminal AC1 of the SE900 (the light
should go off).
5. Check the SCR and Diode for isolation from the mounting housing.
6. If all of the above tests could be performed, the unit is good. If any
of the tests could not be performed, the unit is defective.
