The J1 connector
, located on the rear panel provides analog signals for monitoring the Output Vol
t-
age 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 Out
put Vol
t
age and
Output Current. The monitor ou
t
puts have 500 ohm series output resistance. Ensure that the sensing
circuit has an input resistance of greater than 500 Kohm or accuracy will be r
e
duced.
Refer to Table 6

Notes:
1. Radiated emissions, FCC requir
e
ments:
FCC requirements for radiated emissions; use shielded
cable for the analog control signals. If using unshielded
cable, attach an EMI ferrite suppressor to the cab
le, 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 defined by the encoders or communic
a-
tion.
4. Communication:
In Remote analog mode, all power supply parameters
can be programmed and readback via the communication
port, e
x
cept the Output Voltage and Current setting.
