Both outputs of each power train connected in parallel. The current limit is primary side controlled. In the event of a sustained overload
condition, the thermal protection may cause the converter to shut down (restart on cool-down).
BW = 20 MHz, measured with an external capacitor of 1 µF across the output pins.
Measured with a probe according to EN 61204

The overvoltage protection is via a primary side second regulation loop, not tracking with Trim control.
