Rear Panel Connections (programmable models only)
Non-programmable models have no rear panel connections. The rear panel connections of the
programmable units are shown below:
Output Terminals
The Output terminals are duplicated on the rear panel terminal block; space restrictions limit the
markings to + and − in the group marked OUT. These connections are paralleled with their front
panel equivalents.
Remote sense connections are not available on the rear panel; should an application require remote
sensing then the front sense terminals can be used. 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. Switch back to LOCAL when remote sensing is not in use.
Analog Remote Control
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. These inputs, and their common return signal
(RTN), are isolated from the output; the isolation rating with respect to the output is 300V max. 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. Maximum permissible input is 60V.
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.
Analog Out

Warning! COM is referenced to the output control circuit and will be within ~1V of the
positive output potential. V
Do not apply external voltages to these terminals.
