CONSTANT CURRENT OPERATION
To set up a power supply for a constant current operation, proceed as follows:
a) Turn A-adj control fully counter clockwise to ensure that output decreases to 0 A, and then on power supply.
b) Adjust V-adj control (no load connected) for maximum output voltage allowable(voltage limit), as
determined by load conditions. During actual operation, if a load change causes the voltage limit to be
exceeded, the power supply will automatically crossover to constant voltage operation at the preset voltage
limit and output current will drop proportionately.
c) Adjust A-adj control for desired output current while depressing CC SET button.
d) Push-on DC OUT push button switch for DC voltage output.
CONNECTING LOADS
The output of the supply is isolated from earth ground. Either output terminal may be grounded or the output can be
floated up to 240 volts off ground.
TRACKING OPERATION (MODEL 3033 ONLY)
To select a tracking operation output as follows:
a) Set independent and tracking select switch to tracking position.
b) Depressing CC SET push button switch and adjust A-adj control of the each for maximum output current
allowable(current limit), as determined by load conditions.
c) Adjust V-adj controls (COARSE, FINE) of the MASTER for desired output voltage. This time, V-adj
controls (COARSE and FINE) of the SLAVE should be set on maximum.
d) Connect load using the negative (black) terminal of the SLAVE supply and the positive(red) terminal of the
MASTER supply.
e) Push DC OUT switch of both.
