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 required J1 connection, SW1-4 setting and monitoring voltage range.

Table 6-5 Monitoring signals setting
FCC requirements for radiated emissions, use
shielded cable for the analog control signals. In case of
using unshielded cable, attach an EMI ferrite
suppressor to the cable, as close as possible to the
power supply.
In Remote analog mode the output voltage and
current can't be set by the VOLTAGE and CURRENT
encoders.
Use PREV button to display the output voltage and
current setting defined by the encoders or
communication.
In Remote analog mode, power supply parameters
can be programmed and readback via the
communication port except output voltage and current
setting.
