Remote programming in series operation for increased output voltage:
1. Programming by external voltage:
The analog programming circuits of this power supply are
referenced to the negative Sense (-S) potential. Therefore, the
circuits used to control each series connected unit must be
separated and floated from each other using the
Isolated Analog option.
2. Using the SO function and
PS_OK signal:
The Shut-Off and PS_OK circuits are referenced to the isolated
interface common, IF_COM (J1-2,3). The IF_COM terminals of
different units can be connected to obtain a single control circuit
for the power supplies connected in series.
See Section 6.3 for details.
3. Programming by external resistor:
Programming by external resistor is possible.
Refer to Section 7.5 for details.
4. Programming via the Serial
Communication port
(RS232/RS485):
The communication port is referenced to the IF_COM 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. Refer to Chapter 8 for details.
