Polarity and overload protective circuit for electric consumers |
摘要 |
The protective circuit against overpoling and overloading of an electronic consumer includes a combination of a zener diode connected parallel to the consumer and a parallel connection of a fuse and a conventional diode connected in series with one power supply terminal. Preferably an additional fuse is connected in series between the power supply and the first-mentioned fuse. In the case of a polarity reversal, a fuse burns out, but after restoring normal operational conditions the protective circuit permits operation of the consumer.
