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 switches and make connections to a connector on the
power supply rear panel. See Section 4.2 Switches and Connector Used for Remote Programming and
Monitoring.

Remote Analog Programming Procedure

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.

1.

Shut the power supply OFF.

2.

Set switches SW1-1, SW1-2, SW1-3, and SW1-4 according to the programming sources you will be
using, as indicated in Table 4.3-2. See Notes at the end of this procedure for more information about
switch settings.

3.

Install any J2 connector jumpers as indicated in

Table 4.3-2.

4.

Connect the programming source(s) to the rear panel J2 connector as shown in Figure 4.3-1, observing
the correct polarity for voltage sources.

5.

Set the programming sources to the desired levels and turn the power supply ON. The REM LED turns
on. Adjust the external programming source to change the power supply's output.
