Remote programming in series operation for increased Output voltage:
1. Programming by external voltage: The Remote Analog programming circuits of this Power Supply
are referenced to the negative local sense (-LS) potential.
Therefore, the circuits used to control each series connected unit
must be separated and floated from each other using the
Isolated Analog interface 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 together to obtain a single
control circuit for the power supplies connected in series.
See Section 6.5.1 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
(RS-232/RS-485):
The communication port is referenced to the isolated interface
common, IF_COM (J1-2, -3), which is isolated from the Power
Supply output potential. Therefore, power supplies connected in
series can be daisy-chained using the Remote-In and Remote-
Out connectors. Refer to Chapter 8 for details.
