CONTROLS AND INDICATORS
“A” SUPPLY CONTROLS AND INDICATORS
16. C.C. (Constant Current) Indicator. Red LED lights when
“A” supply is in the Constant Current mode. The Power
Supply regulates the output current at the value set by the
“A” CURRENT control. In the Parallel Tracking mode,
when this indicator is lit, both the “A” and “B” supplies are
in the Constant Current mode.
17. C.V. (Constant Voltage) Indicator. Green LED lights when
the “A” supply is in the Constant Voltage mode. The Power
Supply regulates the output voltage at the value set by the
“A” VOLTAGE controls. In either the Series or Parallel
Tracking mode, when this indicator is lit, both the “A” and
“B” supplies are in the Constant Voltage mode.
18. Coarse VOLTAGE Control. Coarse adjustment of the
output voltage of the “A” supply. Also functions as coarse
adjustment control for the maximum output voltage of the
“B” supply when either parallel or series tracking mode is
selected. Read the value on the “A”/4-6.5 V LED Display
when the voltage (V) and master (0-30 V) metering modes
are selected.
19. Fine VOLTAGE Control. Fine adjustment of output
voltage of the “A” supply. Also functions as fine adjustment
control for the maximum output voltage of the “B” supply
when either parallel or series tracking mode is selected. Read
the value on the “A”/4-6.5 V LED Display when the voltage
(V) and master (0-30 V) metering modes are selected.
10. CURRENT Control. Adjusts current limit of “A”
supply in constant voltage mode. Adjusts constant
current value of “A” supply in constant current mode.
Current can be read from the “A”/4-6.5V LED Display
when the current (A) and master (0-30V) metering
modes are selected.
11. “+” Terminal (Red). Positive polarity output terminal
for the “A” supply. Also serves as the positive polarity
terminal for 4 A parallel and 0-to-60 V series tracking
operation.
12. Terminal (Green). Earth and Chassis Ground.
13. “-” Terminal (Black). Negative polarity output terminal
for the “A” supply. Also serves as the negative polarity
terminal for 4 A parallel tracking operation. In series
tracking operation, this terminal is internally tied to the
(+) positive terminal of the “B” supply.
“B” SUPPLY CONTROLS AND INDICATORS
14. C.V. (Constant Voltage) Indicator. Green LED lights
when the “B” supply is in the Constant Voltage mode.
The Power Supply regulates the output voltage at the
value set by the “B” VOLTAGE controls.
15. C.C. (Constant Current)/PARallel Indicator. Red
LED lights when “B” supply is in the Constant Current
mode. The Power Supply regulates the output current at
the value set by the “B” CURRENT control when in the
series tracking or INDEPendent modes. Also lights
when the TRACKing PARallel mode is selected.
