Electronic contact with associated power limiting means. |
摘要 |
<p>Electronic contacts and associated devices include a voltage protection device (D1 to D5, Q4, Q5, Q7) and a current protection device (R2, Q4, Q6, Q7) for placing an electronic contact (TRX) in the open state when the voltage across and the current flowing in the latter exceed a predetermined voltage (VD) and current (I1) values respectively. The predetermined voltage value (VD) is slightly larger than the one (V1) which corresponds to the predetermined current value (I1) in the current versus voltage characteristic of this electronic contact.</p> |
