Remote Analog Programming of Output Voltage and Current Limit
Release 2.1 75
4. Connect the programming source(s) to the mating J2 connector as shown in
Figure 4.1, observing the correct polarity for voltage sources. Ensure that the
mating connector is plugged securely into the rear panel connector.
5. Set the programming sources to the desired levels and turn the power supply ON.
The REM LED turns on.
6. Adjust the external programming source to change the power supply’s output.
Notes:
1. Switches SW1 to SW4 can be set to their defaults (all open) unless otherwise
specified in Table 4.2. Switches SW1-5, SW1-6, SW1-7, and SW1-8 are not
required for remote programming. They can remain at the settings you have
selected for your application.
2. Resetting switches SW1-3 or SW1-4, the programming scale selection switches,
may require that you recalibrate the programming circuit to maintain
programming accuracy. See Section 5. Calibration.
3. Any of the eight switches on SW1 is OFF (OPEN) when it has been flipped up
to break contact, ON (CLOSED) when flipped down to close contact.
4. The control circuits have been designed to allow you to set output voltage and
current up to 5% over the model-rated maximum values. The power supply will
operate within these extended ranges, but we cannot guarantee full performance
to specification.
