Parallel and Series Connection
Single- or double-output models with equal output voltage can
be connected in parallel without any precaution by inter-
connecting the T-pins for equal current sharing; see fig. 9a.
Double-output models with their outputs connected in parallel
behave exactly like single-output models, and are fully
regulated. There is no inconvenience or restriction using R-
input sense lines.
Single-output and/or double-output models can be connected
in series. For double-output models with both outputs
connected in series, consider that the effect via sense lines, R-
input or option P is doubled. See fig. 9b.
Parallel configuration of double-output models with both
outputs connected in series is shown in fig. 9c. It is essential
that the Vo1– pins of all paralleled converters are connected
together, as the auxiliary signals are referenced to Vo1– or to
S–. The effect via sense lines, R-input or option P is doubled.

connect it in parallel to the main output to maintain good
regulation.
always include main and second output to produce good
regulation.
Series connection of second outputs without involving their main
outputs should be avoided as regulation may be poor.
The maximum output current is limited by the output with the
lowest current limit, if several outputs are connected in series.
Rated output voltages above 48 V (SELV = Safety Extra Low
Voltage) need additional measures in order to comply with
international safety requirements.
