Most CONCEPT drivers do not limit the input current  respectively the output power of the driver module. This means that they are not permanently protected from short circuits at their outputs. The advantage of this design is that the drivers may be briefly overloaded. The corresponding data sheets show the relevant limitations of this mode.

A typical application case would be burst operation (see also FAQ on this topic) when high-frequency switching phases alternate with suitable pauses. Another case is represented by pulsed-power topologies, which also require very high peak loads although the average power drawn is significantly lower.

The advantages of these special operating modes have led to us at CONCEPT to dispense with a general hard short-circuit protection of the drivers and to configure the input load limit in a flexible way.
