An overload protection circuit for an electrical signal source is disclosed in which an overcurrent in the signal source is sensed and the source is disabled for a predetermined time interval. If the overcurrent condition persists beyond the predetermined time interval, the turn-off cycle is repeated. The system is immune to overcurrent transients and the amplitude of the current which triggers turn-off, as well as the length of the predetermined time interval, may be selectively set. |
