Generating complementary output voltage
Another common requirement in industrial application is to provide a complementary voltage (e.g. ±5V). The circuit below
shows how this target can be achieved by simply combining two 1779205x4 used in a standard configuration (delivering a
positive output voltage) with a 1779205x4 in reverse configuration.

Note: A decoupling filter is present to avoid oscillations between the two Power Modules. The decoupling filter doesn´t
replace the EMI input filter.
