Power switch
: ON/OFF the power input.
1
V LED display
: Indicates the MASTER output voltage.
3
V LED display
: Indicates the SLAVE output voltage.
2
A LED display
: Indicates the MASTER output current.
4
A LED display
: Indicates the SLAVE output current.
5
Voltage control
: For adjustment of the output voltage of the MASTER supply. Also functions
as adjustment control for the maximum output voltage of the SLAVE supply
when either parallel or series tracking operation.
7
Voltage control
: For adjustment of the output voltage of the SLAVE supply when the
independent operation.
6
Current control
: For adjustment of the output current of the MASTER supply. Also functions
as adjustment control for the maximum output voltage of the SLAVE supply
when either parallel or series tracking operation.
8
Current control
: For adjustment of the output current of the SLAVE supply.
9
Over load indicator
: Lights when load on 5 volt supply becomes too large.
10
C.V indicator
: Lights when the MASTER supply is in the constant voltage operation, in
either the Series or Parallel Tracking mode, both the MASTER AND SLAVE
supplies are in the constant voltage operation.
12
C.V indicator
: Lights when the SLAVE supply is in the constant voltage operation.
11
C. C. indicator
: Lights when the MASTER supply is in the constant current operation.
13
C. C. indicator
: Lights when the SLAVE supply is in the constant current operation. Also
lights when the TRACKING PARALLEL mode is selected.
14 & 15
TRACKING Mode Switches:
Two push-button switches that select INDEPENDENT mode, SERIES TRACKING mode, or
PARALLEL TRACKING mode as follows:
a) When both switches are disengaged (out), the unit is in the INDEPENDENT mode and the
MASTER and SLAVE power supplies are completely independent from one another.
b) When the left switch is engaged (in) and the right switch is disengaged (out), the unit is in the
TRACKING SERIES mode.
In this mode, maximum voltage of both supplies is set using the MASTER VOLTAGE controls
(voltage at output terminals of the SLAVE supply tracks the voltage at the output terminals of
the MASTER supply). Also, in this mode of operation the positive terminal (red) of the SLAVE
supply is connected to the negative terminal (black) of the MASTER supply.
This allows the two supplies to be used as one 0 to double rating voltage supply.
c) When both switches are engaged (in), the unit is in the TRACKING PARALLEL mode. In this
mode the MASTER and
SLAVE supplies are wired together in parallel and both the maximum current and voltage are
set using the MASTER controls. The MASTER and SLAVE outputs can be used as two
individual (but tracking) power supplies or just the MASTER output can be used as a 0 to rating
voltage supply with a 0 to double rating current capability.
