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 o
f 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 ci
rcuit
has an input r
e
sistance of greater than 500 Kohm or accuracy will be reduced.
Refer to Table 6

5 Monitoring signals setting
Notes:
1. Radiated emissions, RCC requir
e
ments:
FCC requirements for rad
iated 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
commun
i
cation.
4. Communication:
In Remote ana
log mode, all power supply parameters
can be programmed and readback via the communication
port, except the Output Voltage and Current setting.
