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 ohms of series
output resistance. Ensure that the sensing circuit has an input resistance of greater than
500kOhms or Output voltage/Output current accuracy will be reduced.
Refer to Table 7-5 for required J1 connections, SW1-4 settings and monitoring voltage
ranges.

Table 7-5 Monitoring Signals Setting
FCC requirements for radiated emissions use shielded cable for
the analog control signals and connect the shield to chassis (A
stud is provided near J1).
In Remote Analog mode the Output voltage and Output current
can't be set by the VOLTAGE and CURRENT encoders.
Use the PREView button to display the Output voltage and
Output current setting defined by the encoders or Digital
communication.
Remote Analog mode - Power Supply parameters can be
programmed and readback via the Digital communication port
except the Output voltage and Output current setting.
