Automatic Voltage Regulator PCB
Interchangeable:
F9719
0F9719
0830490SRV
81918
83049
083049
83049GS
SRV83049
0F97190SRV
However, 083049 and 0F9719 require longer bolts when replacing 083048 due to the thicker heat sink.
Note
After we install the new voltage regulator, the most critical thing is still to make sure that the frequency is correct, the first choice is to set the mechanical governor to no-load 62 Hz, then set the electronic governor to no-load 60 Hz, then measure the AC output, The voltage at no load 60 Hz should be 120 VAC, and at no load 62 Hz should be 124 VAC, if the voltage difference is too large or too small, please adjust the brass screw on the blue trim potentiometers next to the red LED to the correct voltage if necessary If the voltage difference is too large or too small, please adjust the brass screw on the blue trim potentiometers next to the red LED to the correct voltage if necessary.
