    Functional Description
    The input voltage is fed via an input fuse, an input filter, and
    an inrush current limiter to the input capacitor. This capaci-
    tor sources a single transistor forward converter. Each out-
    put 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 filter.
    The control logic senses the main output voltage
    Uo1 and
    generates, with respect to the maximum admissible output
    currents, the control signal for the primary switching tran-
    sistor.
    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.
