2.3.1 AC Input
The LA Stand-Alone amplifier can accept AC input voltages of 100 – 120 and 208 - 240VAC at 47 – 63Hz.
Note that the Stand-Alone amplifier utilizes an unregulated linear power supply. Therefore a higher AC
input (for a given range) will provide a higher voltage to the spindle and allow the spindle to reach higher
velocities.
The AC Inlet should be configured per the table below.

2.3.1.1 Changing the AC input configuration
1. Remove power from the AC Inlet
2. Use a flat tipped screwdriver to open the window that covers the red voltage value.
3. Use the screw driver to remove the fuse block.
4. Use the table above to determine the correct fuse value.
5. Reinstall the fuse module such that the correct voltage value will show through the window.
6. Close the window.
