Rear Panel Connections
Non-programmable models have no rear panel connections. The rear panel connections of the
programmable units are shown below:
Main Output and Sense Terminals (all Programmable models)
The Output and Sense terminals are duplicated on the rear panel terminal block marked Output+,
Output −, Sense + and Sense − ; space restrictions on the single units limit the markings to +, −,
S+ and S− in the group marked OUT. These connections are paralleled with their front panel
equivalents.
Switch the LOCAL/REMOTE switch to REMOTE when remote sensing is required. When the
rear panel Output terminals are used, the use of remote sense is always recommended to ensure
that output regulation is maintained within specification; connections can be made to either the
front or the rear remote sense terminals but never to both pairs of terminals at the same time.
Switch back to LOCAL when remote sensing is not in use.
Analog Remote Control (Single Programmable models only)
Connections CV and CC provide analog control of the Output Voltage and Current Limit
respectively when slide switches CV and CC are set to Remote. The input scaling can be set
independently, by internal links, as 0 to 5 Volts (the factory default) or 0 to 10 Volts for 0 to 100%
of maximum output. The COMmon return signal is referenced to the positive output of the power
supply. CV and CC can be used independently or together.
Return slide switches CV and CC to Local when analog remote control is not in use.
Do not apply external voltages between the terminals exceeding the maximum for the selected
range (5V or 10V).
