Remote Analog Programming of Output Voltage and Current Limit

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 18.

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.

1.Turn the power supply OFF.

2.Using Table 4.2, set switches SW1-1, SW1-2, SW1-3, and SW1-4 according to the selected programming sources. See the Notes at the end of this procedure for more information about switch settings.

3.Install any J2 connector jumpers as indicated in Table 4.2.
