GENERAL CONTROLS AND INDICATORS

1. POWER Switch. Turns power on and off.
2. TRACKING Mode Switches. Two pushbutton switches that select
INDEPendent mode, SERies tracking mode, or PARallel tracking
mode as follows:
a. When INDEP/TRACK switch is disengaged (out), the uni t is in
the INDEPendent mode and the "A" and "B" power supplies are
completely independent from one another.
b. When the INDEP/TRACK switch is engaged (in) and the
SER/PAR switch is disengaged (out), the unit is in the TRACK-
ing SERies mode. In this mode, maximum voltage of both
supplies is set using the "A" VOLTAGE controls (voltage at
output terminals of the "B" supply tracks the voltage at the
output terminals of the "A" supply). Also, in this mode of
operation the positive terminal (red) of the "B" supply is
internally connected to the negative terminal (black) of the "A"
supply. This allows the two supplies to be used as one 0-to-60
volt supply.
c. When both INDEP/TRACK and SER/PAR switches are engaged
(in), the unit is in the TRACKing PARallel mode. In this mode
the "A" and "B" supplies are wired together in parallel and both
the maximum current and voltage are set using the "A" controls.
The "A" and "B" outputs can be used as two individual (but
tracking) power supplies or just the "A" output can be used as a
0-to-30 volt supply with a 4 A capability.

When this switch is in the 0-30V position (out), the LED
display monitors the "A" (0-30 V) supply. When this switch is
in the 4-6.5V position (in), the LED display monitors the 4-
6.5V supply.

setting of 0-30 V/4 -6.5 V switch). When in the A (amps)
position (in), current is read from the "A"/4-6.5 V LED
Display. When in the V (volts) position (out), voltage is read
from the "A"/ 4 -6.5 V LED Display.
