CAUTION
To maintain the power supply isolation and to prevent ground loops, use an
isolated programming source when operating the power supply via remote
an
a
log programming at the J1 connector.

REMOTE VOLTAGEPROGRAMMING OF OUTPUT VOLTAGE AND CURRENT
LIMIT
Perform the following procedure to set the power supply to Remote Voltage programming:
1.
Turn the power supply AC On/Off
switch to Off.
2.
S
et setup switch SW1
-
1 to its UP position for output voltage external programming and
SW1
-
2 to its UP position for output current.
3.
Set SW1, position 3 to select the programming voltage range according to Table 6
-
3.
4.
Ensure that SW1, positions
7 and 8 are at their DOWN (default) position.
5.
Connect a wire jumper between J1
-
8 and J1
-
12 (refer to Table 4
-
4).
6.
Connect the programming source to the mating plug of J1 as shown in Fig.6
-
1. Observe
correct polarity for the voltage source.
7.
Set the programm
ing sources to the desired levels and turn the power supply ON. Adjust
the programming sources to change the power supply output.
NOTES:
1.
SW1, positions, 4, 5, 6 and 9 are not required for remote programming. Their settings can
be determined according the
application.
2.
The control circuits allow the user to set the Output Voltage and Output Current up to 5%
over the model
-
rated maximum value. The power supply willoperate within the extended
range, however it is not recommended to operate the power supply ov
er its voltage and
current ra
t
ing, and performance is not guaranteed.
