Parallel and Series Connection
The first outputs of power trains with equal nominal output
voltage can be connected in parallel. Where available, we
recommend ordering of option T.
Any output can be connected in series with any other output.
If the main and the tracking output of the same power train are
connected in series, consider that the effect of the R-input is
doubled.

outputs with option T have current-share pins (T or T1), which
must be interconnected. For other outputs, the load lines
should exhibit similar resistance. Parallel connection of

Parallel operation of two double-output converters with
series-connected outputs is shown in fig. 10. The link
between the T1 pins ensures proper current sharing, even
though only the first outputs are influenced by T1. Sense
lines are connected directly at the connector, and load lines
have equal length and section.

Redundant Systems
An example of a redundant system using converters with 2
regulated ouputs (xP2020) is shown in fig. 11. Load 1 is
powered with 5.1 V and load 2 with 12 V.
The converters are separated with ORing diodes. If one
converter fails, the remaining one still delivers the power to
the loads. If more power is needed, the system may be
extended to more parallel converters (n+1 redundancy).
Current sharing of the 5.1 V outputs is ensured by the
interconnected T1 pins, whereas the sense lines are
• Rated output voltages above 48 V (SELV = Safety Extra Low
Voltage) require additional safety measures in order to comply
with international safety requirements.
