Remote Programming of Output Voltage and Current Limit

Remote Programming of Output Voltage and Current Limit
Remote programming allows control of the power supply's output voltage and/or
current limit to shift from local operation at the front panel voltage and current
controls to external analog input sources. As a programming source is varied, the
power supply's output varies proportionally over its output range.
The analog programming signals are connected to the rear panel J3 connector. To
provide the lowest noise performance, use shielded-twisted pair wiring for making
connections from external circuits to the J3 connector. Use the shortest leads
possible. Ground the shield to pin 6 on the J3 connector or to the chassis via one of
the J3 connector screws.

The remote programming input is internally referenced to the supply's negative
output. Do not connect remote programming input lines (J3 pins 9 and 10) to the
supply's positive output.
