OUTPUT TERMINAL PANEL CONNECTIONS
UVWO Terminal Output Voltages
Various output voltages can be obtained using the UVWO output terminal lugs. The voltages at the terminals are dependent on the position of the Voltage Selector Switch and the adjustment of the Voltage Regulator Control Knob.
Remember the voltage selector switch determines the range of the output voltage. The voltage regulator (VR) allows the user to increase or decrease the selected voltage.
3.Turn the voltage regulator knob (Figure 21) clockwise to increase voltage output, turn counterclockwise to decrease voltage output. Use voltage regulator adjustment knob whenever fine tuning of the output voltage is required.
