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 Cur-
rent. 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 reduced.
Refer to Table 6-5 for the required J1 connection, SW1-4 setting and monitoring voltage range.

Notes:
1. Radiated emissions, RCC requirements: FCC requirements for radiated emissions; use a shielded
cable for the analog control signals. If using unshielded ca-
ble, 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 current
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 Cur-
rent setting, as defined by the encoders or digital communi-
cation.
4. Communication:
In Remote analog mode, all power supply parameters can
be programmed and readback via the communication port,
except the Output Voltage and Current setting.
