OPERATING INSTRUCTIONS
1. Check the voltage rating of the equipment to be powered. Care must be taken not to exceed this rating.
2. Plug the line cord into a 120V, 60Hz AC outlet.
3. Adjust the voltage control to desired voltage. Load variation will have practically no effect on the voltage
setting due to the special regulation circuit.
4. Connect the positive lead of your equipment to the red output terminal and the negative lead to the black
terminal when using the positive supplies. For the negative voltage use the yellow terminal.
5. Care must be taken not to exceed the current reading, as the supplies will turn themselves off if overheated.
6. The Model XP-620 has an added feature of having the positive and negative supplies being able to be stacked
to give up to 30V at 1 ampere. Simply use the negative 1.5 to 15V output (yellow jack) as your minus supply
connection. For the positive connection, use the positive 1.5 to 15V red terminal. This will allow you to obtain
a variable 3V to 30V at up to 1 ampere out.
