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-720 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 1.25 to 15V output (yellow jack) as your minus
supply connection. For the positive connection, use the positive 1.25 to 15V red terminal. This will allow you
to obtain a variable 2.5V to 30V at up to 1 ampere out.
CAUTION: The maximum output current for the AC section is 1 amp. Overloading the output or shorting the
6.3VAC to ground will damage the transformer.
