Remote Analog Control
(Single programmable models only)
Remote analog control of output voltage and current is possible using variable external control
voltages applied between the rear panel CV and COM or CC and COM inputs respectively.
The Analog Out control voltages V
out
and I
out
of one unit acting as a ‘master’ can be used to
control a ‘slave’ unit via the slave’s CV and CC inputs respectively.
Analog Voltage Control
Remote analog voltage control is achieved by setting the rear panel CV switch to Remote and
applying a programming voltage between the inputs CV and COM.
The front panel VOLTAGE controls are disabled when Remote is set on the CV switch. Set the
switch to Local to return control to the front panel.
The default input voltage scaling is 0V to 5V for 0 to 100% of the rated output voltage. The input
voltage scaling can be changed to be 0V to 10V by removing an internal shorting link.
Disconnect the instrument from the AC source and remove the cover as described in the
Installation section. Referring to the top view of the instrument shown in the drawing, remove the
tall shorting link in position LK1.
Remote CV can be used with either Local or Remote CC.
Analog Current Control
Remote analog constant current control is achieved by setting the rear panel CC switch to
Remote and applying a programming voltage between the inputs CC and COM. Remote analog
current control can only be used on the high current range, not the 500mA range.
The front panel CURRENT control is disabled when Remote is set on the CC switch. Set the
switch to Local to return control to the front panel.
The default input voltage scaling is 0V to 5V for 0 to 100% of the rated maximum current (high
range only). The input voltage scaling can be changed to be 0V to 10V by removing an internal
shorting link. Disconnect the instrument from the AC source and remove the cover as described
in the Installation section. Referring to the top view of the instrument shown in the drawing,
remove the tall shorting link in position LK3.
Remote CC can be used with either Local or Remote CV.
CAUTION . Do not apply external control voltages to either the CV or CC input that exceed the
maximum for the set input range (5V or 10V). The inputs are protected against excess voltages
but the instrument will attempt to supply an output voltage or current in excess of its maximum
rating if the control voltage exceeds its range limit, with possible consequential damage. If the
condition persists, OVP and/or OCP may trip the output off, see next section.
