3. Programming by external resistor:
Programming by external resistor is possible. Refer to
Section 6
-
5 for details.
4. Programming via the Serial
T
he communication port is referenced to the IF_COM
Communication port (RS232/RS485):
which is isolated from the power supply output potential.
Therefore power supplies connected in series can be
chained using the Remote
-
In and Remote
-
Out connectors.

5.14.2 Series connection for positive and negative output voltage
In this mode, two units are co
n
figured as a positive and negative output. Set the current limit of each
power s
upply to the maximum that the load can handle without damage. It is recommended that diodes
be connected in parallel with each unit output to pr
e
vent reverse voltage during start
-
up or in case one
of the units shuts down. Each diode should be rated to at l
east the power supply rated ou
t
put voltage
and output current. Refer to Fig.5
-
3 for this operating mode.
Remote programming in series operation for positive and negative output voltage
1.
Programming by external voltage:
The analog programming circuits
of this power supply are
referenced to the negative Sense (
-
LS) potential. There
-
fore the circuits used to control series connected unit
must be separated and floated from each other.
2.
Using the SO function and PS_OK:
The Shut
-
Off and PS_OK circuits ar
e referenced to the
is
o
lated interface common, IF_COM (J1
-
2
-
3). The
IF_COM terminals of the units can be connected to obtain
a single control circuit for the power supplies connected
in series.
