Changing PC3A Voltage
In most cases, you will not need to change the voltage on your PC3A. However, since different
countries use different standard voltage settings, there may be times when you need to make the
change.
The PC3A’s fuse holder (where the power cable plugs in) is where you change the voltage. The
marks on the fuse holder are 115 and 230. 115 should be used for voltages from 100 to 125. 230
should be used for 200 to 240. Generally, North America uses 115, and Europe and Asia/
Australia use 230, but there are exceptions to this general rule.
The PC3A uses two 250 mA fast blow fuses for 230V or two 500 mA fast blow fuses for 115V.
These can be either 1.25” X 0.25” size or 5 mm X 20 mm size fuses. Extra fuses are not provided,
so you will need to acquire the correct fuse before you change the voltage.
Removing the fuse holder
Remove the power cord.
Pry open the fuse holder cover. Use a thin tool inserted into the hole where the red voltage
indicator shows through.
Pull up gently to open the fuse holder cover. The cover is hinged next to the power cord
connection.
