Functional Description
The input voltage is fed via an input fuse, an input filter, a
rectifier and an inrush current limiter to the input capacitor.
This capacitor sources a single transistor forward converter.
Each output is powered by a separate secondary winding of
the main transformer. The resultant voltages are rectified
and their ripples smoothed by a power choke and output fil-
ter. The control logic senses the main output voltage

and generates, with respect to the maximum admissible
output currents, the control signal for the primary switching
transistor.
The second output of double output units is controlled by
the main output but has independent current limiting. If the
main output is driven into current limitation, the second out-
put voltage will fall as well and vice versa.
