13- Application Notes
13-1 Connection of Outputs in Series
Any of the bi output converters can be configured to produce
an output of 10V (+/ -5 output models), 24V (+/ -12V out-
put models), or 30V (+/ -15V output models) by connecting
the load across the output (+) and the output (-) with
either output grounded, and leaving the common pin
floating.

13-2 Connection of Modules in Series

Vo
The output of single output units can be connected in
series without any precautions to provide higher output
voltage level.
Nevertheless, GAIA Converter recommends to protect each
individual output by a low power shottky diode rated with
the maximum current of the converter to avoid reverse
polarity at any output.
Reverse polarity may occur at start up if the output volta-
ges do not rise at the same time.

13-3 Connection of Modules in Parallel
Several converters with equal output voltage can be
connected in parallel to increase power. Nevertheless some
cares have to be taken in particular as the output voltage
of each converter is slightly different, when paralleling,
the converter with the highest output voltage will source
the most current.
However the GAIA Converter modules are designed with a
“soft’’ output voltage versus current characteristic. This
causes the output voltage of each converter to automatically
adjust downward as its current increases so each converter
very approximately shares the total output current. It is
important that each converter has approximately the same
impedance between their output and the common load.
