*) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. There is no
guarantee that this value can be achieved. The typical value achievable by turning the potentiometer to the clockwise end position
is 15.7V.

Peak current capability (up to several milliseconds)
The power supply can deliver a peak current which is higher than the specied short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.
The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be
discharged and cause a voltage dip on the output. Detailed curves are provided in section 20.1.
Peak current voltage dips typ. from 12V to 7.8V at 2.6A for 50ms, resistive load
typ. from 12V to 5.2V at 6.5A for 2ms, resistive load
typ. from 12V to 2.0V at 6.5A for 5ms, resistive load
