6.6 Remote Monitoring of Output Voltage and Current
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 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 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 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 Current setting, as defined by
the encoders or digital communication.
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.
