Remote Analog Programming of Output Voltage and Current Limit
TM-F2OP-C1XN-01 4-3
Remote Analog Programming of Output Voltage and
Current Limit
Remote analog 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 sources. As you vary the
external programming source, the power supply’s output varies
proportionally over its output range.
Using remote analog programming requires that you reset switch SW1
and make connections to the J2 connector on the power supply’s rear
panel. See “Rear Panel Connectors and Switch” on page 1–5.
Remote Programming Options
See Table 4-1 for a summary of the options available to you for
programming output voltage and current limit using an analog source.

0-5 k and 0-10 k resistances
CAUTION
To maintain the isolation of the power supply output and prevent ground loops,
use an isolated (ungrounded) programming source when operating the power
supply via remote analog control at the J2 connector.
CAUTION
The remote programming inputs are internally referenced to the supply’s
negative output. Do not connect control ground (J2 terminals 3, 5, or 7) to the
supply’s positive output.
