<p>The fuse monitor has a l.e.d. (4) in parallel with the fuse and in series with a circuit (6) consisting of a PTC resistor (7) in parallel with an ordinary resistor (8). The series circuit consisting of the l.e.d. and the circuit (6) is in parallel with the fuse (2). The l.e.d. (4) can be placed in a branch of a bridge rectifier, the other branches being connected to the fuse and the circuit. A further l.e.d. (5) can be connected in antiparallel to the first (4).</p> |
