Title: Direct current supply circuit - is for load with means preventing flow of load current exceeding specified limit
Inventor: TSCHAB NORBERT
IPC: H02H9/02
Filed: 1975-06-07
Abstract: The d.c. supply circuit consists of a current source and a fuse whose rated current is below the above limit. When blown, it irreversibly disconnects the load from the source. A transistor current limiting circuit limits the load current rising above the fuse (6) rated current so that it does not exceed the limit. Load current so limited blows the fuse. The base and collector fo the first transistor are bridged by a resistor (9). The second transistor circuit has a measuring resistor (10) between the collector and the base terminals.
