This compact power supply unit is characterised by the variety of application possibilities and low system costs. The fact that the external
fuses are no longer necessary is an advantage as it saves cost and
space. The selectable FUSE Mode and the fully specified 2-phase
operation make the SL10.305 the unit of choice.
