Abstract
An overload protection circuit for power supplies and telecommunications apparatus such as multifrequency ringing generators causes the output voltage to become zero when a current overload is detected. The voltage is kept at zero for a predetermined period of time. Then the output voltage is restored. If an overload is still detected, the output voltage is again brought to zero.
