The voltage and current of the master can be set by either the front panel controls, via the digital
interface, or by an external voltage applied to its own CV and CC analogue control inputs.
In constant voltage mode the voltage across the load is that set on the master unit by its front
panel controls, via the digital interface or by the analogue CV remote control input. The current
limit for the system (i.e. the current in constant current mode) is the current limit set on the master
x n, where n is the total number of units connected in parallel.
Isolated or Series Operation in Master-Slave Configuration
Isolated or Series operation in Master-Slave configuration permits tracking output voltages and
current limits to be set for multiple units from a single instrument. The diagram shows 2 units
connected in series for tracking ±Volts and tracking current limits. Connect the V
of the master to the CV, CC and RTN inputs of the slaves (set CV and CC switches to Remote) as shown.
The diagram shows remote sense connections to the load; set the front panel sense switch to Remote.
If remote sensing is not required, do not use the sense wires and set the sense switch to Local.
If independent current limits are required set CC to Local and set the limits from the front panel of
each unit.
Warning! In series operation take care not to exceed the maximum rated operating voltage
(300V) of any terminal with respect to earth ground (
Remote Off
A switch closure or logic low between the rear panel Rem Off and COM inputs will remotely turn
off the output if it was previously on; the front panel OUTPUT lamp will also go off. Opening the
switch between Rem Off and COM will turn the output on again.
Warning! COM is referenced to the output control circuit and will be within ~1V of the
positive output potential.
