3. Series connection for bipolar output voltage:
the current limits of each power supply to the maximum that the load can handle without damage. It is
recommended to connect diodes in parallel to each unit output to prevent reverse voltage during start-
up condition or in case one of the units shuts down. Each diode should be rated to at least the power
supply’s output current. Refer to Fig. 4-14 for this operating mode.
3.1 General: At this operation mode, two units are configured as a bipolar voltage/current source. Set
3.2 Remote programming at series operation for bipolar output voltage:
1. Programming by external voltage; The analog programming circuits of the ZUP power supply
2. Programming by external resistor: Programming by external resistor is possible. Refer to
3. Programming via the communication port (RS232/RS485): The communication port is isolated
are referenced to the - Sense potential. Therefore, the circuits used to control each unit must
be separated and floated from each other.
Fig. 4-5 and Fig. 4-6 for details.
from the output voltage, therefore the serialy connected power supplies can be chained using
the Remote-In and Remote-Out connectors.
