120V Input Power & Field Connection Diagram
(
See pages 10-12
for control wiring information)
The XC14/XC15
is a Half-Wave rectified voltage regulator, which allows a maximum of
52VDC at 20 ADC with an input voltage of 120VAC.
This connection is typically used on generators with full load field voltages of 32VDC or
less and full load exciter field amperage less than 12ADC.
Note that the maximum input voltage to the XC14/XC15
Voltage regulator in this
connection is 139VAC!
DO NOT input 208-240VAC into the XC14/XC15
in this
connection!
Regulation problems or damage to the unit may result! For use on 480V
systems, use a
480-120V step-down transformer rated at 1KVA
or connect the
regulator to the winding center taps T7 and T0 (
See Pages 6 and 7
)
.
Using a transformer to connect the input of the XC14/XC15
to 2 different phases of the
generator will result in greater regulation accuracy than when connecting line-neutral.

For 480V Generators, use a 1KVA
(or
larger)
Transformer
with a
120V
Secondary
OR
Connect to the Generator
winding center taps at
T7 and T0.
NEVER install a switch or
breaker on the DC or Exciter
side of the voltage regulator!
Only install a switch or
disconnect on the AC Side of
the regulator!
