Connect to AC.100 to 120V or AC. 200 to 240V input line.
Connect to AC.100 to 120V or AC. 200 to 240V input line.
Connect to earth ground. This is connected to the case.
The output voltage can be turned on and off from an external source by inputting the external signal
between these terminals. RC terminals are floating.
These terminals are used to compensate voltage loss from the output terminal to a load.
DC output terminals are shorted with a metal bar.
Connect to load.
Adjusts output voltage.
Turn clockwise to increase the voltage.
This Green LED becomes indicated when voltage is output.
Turn the remote on/off switch located at the center of the power supply to "Y" (clockwise) to enable
the remote control.
