Triangular current limitingPower supplies with a U/I characteristic perform current limiting to typically 1.1 to 1.2 times the rated current at constant output voltage. This current is still available in case of an overload or a short circuit. In this case, the power supply either immediately cuts the output voltage to zero (rectangular current limiting) or performs slow lowering of the output voltage, what, however, can possibly lead to a further increase of the output current (triangular current limiting).
Since the current does not sag in case of an overload, this method enables reliable starting of high loads.
