Switching in current limiting circuit for electronic module fitted in rack, using comparator for comparing reference voltage with operating voltage supplied via charging capacitors defining switching in delay

摘要

The circuit has a comparator (28) associated with the plug-in location (4-19) for the electronic module (20), supplied with a reference voltage and an operating voltage via charging capacitors (35-38) having a different capacitances, the sum of the capacitances determining the switching in delay. A signal for application of the operating voltage to the electronic module is provided when the reference voltage is exceeded.
