Operating Manual for XKW 3kW Series Power Supply
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 following table summarizes access options for programming output voltage and
current limit with the input scales supported for the power supply. Refer to
“Programming Output Voltage and Current Limit with the REM/LOC Switch” on
page 55
for a procedure and a connection diagram for programming output voltage
and current limit using the REM/LOC switch. Subsequent sections provide short
procedures and diagram the J3 connector configurations and connections required
for remote programming of output voltage and/or current limit without using the
REM/LOC switch.

!
CAUTION
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.
