Circuit breaker with undervoltage detection |
摘要 |
A resistor (6) supplies an increased voltage to an operational amplifier (7) if an overcurrent occurs and the output is supplied to a memory block (2). A second operational amplifier (25) becomes conducting and makes a makes a metal oxide switching element (5) non conducting through transistors (27,44). On undervoltage insufficient voltage is available at a Zener diode (42) to keep the metal oxide switching element (5) conducting. .
