    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

    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.
