83-507-5002 Rev. B
The J1 connector, located on the rear panel provides analog signals for monitoring the Output
Voltage and Output Current. Selection of the voltage range between 0-5V or 0-10V is made by
setup switch SW1-4. The monitoring signals represent 0 to 100% of the power supply Output
Voltage and Output Current. The monitor outputs have 500 ohm series output resistance. Ensure
that the sensing circuit has an input resistance of greater than 500 Kohm or accuracy will be re-
duced.
Refer to Table 6-5 for the required J1 connection, SW1-4 setting and monitoring voltage range.

Notes:
1. Radiated emissions, RCC requirements: FCC r equirements for radiated emissions; use a
shielded cable for the analog control signals. If using
unshielded cable, attach an EMI ferrite suppressor to
the cable, as close as possible to the power supply.
2. Front panel encoders operation: In Remote analog mode, the output voltage and cur-
rent can’t be set by the VOLTAGE and CURRENT
encoders.
3. Front panel PREV button: Use the PREV button to display the Output Voltage
and Current setting, as defined by the encoders or
digital communication.
4. Communication: In Remote analog mode, all power supply parame-
ters can be programmed and readback via the
communication port, except the Output Voltage and
Current setting.
