CONTROLS AND INDICATORS
GENERAL CONTROLS AND INDICATORS
8. POWER Switch. Turns power on and off.
9. 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 unit
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
TRACKing 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 en-
gaged (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.
1. 0-30V/4-6.5V Switch. Controls “A”/4-6.5V LED
Display. 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.
2. Right V/A Switch. Selects current or voltage metering
mode for the “A” 0-30 V supply or the 4-6.5 V supply
(depending on 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.
3. “A”/4-6.5 V LED Display. Digital display indicates
voltage or current at the 0-30 V “A” supply or the 4-6.5
V supply (depending on the setting of the Right V/A and
0-30 V/4-6.5 V switches).
4-6.5 V SUPPLY CONTROLS AND INDICATORS
4. “-” Terminal (Black). Negative polarity output terminal
for 4-6.5V supply.
5. “+” Terminal (Red). Positive polarity output terminal
for 4-6.5V supply.
6. Voltage Level Control. Adjusts output voltage for 4-
6.5V supply. Fully counterclockwise rotation adjusts
output voltage to 4V. Clockwise rotation increases
voltage to a maximum of 6.5V (full clockwise rotation).
7. 5 A OVERload Indicator. Lights when load on 4-6.5
Volt supply becomes too large.
