Details
Written by: Newton C. Braga

 

This circuit was found on a Radio Elettronica (Italy) from April 1974. The circuit can still be assembled today by exchanging TR1 for a TIP32, TR2 for a BD136, TR3 and TR4 for BC558. The circuit cuts off the load supply when the current set in R4 and selected by I1 is exceeded. The input can be between 12 and 25 V and the maximum current is 2 A.
