6.4 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT

CAUTION
To maintain the isolation of power supply and prevent
ground loops, use an isolated programming source
when operating the power supply via remote analog
programming at J1 connector.
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. Set setup switch SW1-1 to its UP position for output voltage external programming and
SW1-2 to its UP position for Output Current limit external programming.
3. Set SW1 position 3 to select 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 short 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 programming 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 setting can be
determined according the application.
2.The control circuits allow the user to set the output
voltage and current limit up to 5% over
the model-rated maximum value. The power supply
will operate within the extended range,
however it is not recommended to operate the power
supply over its voltage and current
rating and performance is not guaranteed.

Wenn Sie das Netzteil mit analogen Spannungen
den J - Verbinder ansteuern, verwenden Sie eine
1
isolierte Signalquelle, um Erdschleifen zu vermeiden
und die lsolation des Netzteils zu erhalten.
Hinweise:
.Die Schalter 4, 5, 6 und 9 von SW sind für die
1
Fernprogrammierung nicht relevent. lhre Einstellung
kann der Applikation entsprechend erfolgen.
2.Die Bedienelemente des Netzteiles erlauben es dem
Anwender, Ausgangsspannung und -strom auf bis zu
05% der Nennhöchstwertes einzustellen. Das Netzteil
1
arbeitet in diesem erweiterten Bereich, jedoch sollte das
Netzteil im normalen Einsatz nicht über die Nennwerte
hinaus betrieben werden. Die Spezifikationen der
Ausgangsparameter werden nur innerhalb des
Nennbereiches für Ausgangsspannung und -strom
garantiert.
