  • Patent number: 5455469
    Abstract: A delay-on-break circuit adaptable for A.C. or D.C. applications utilizes a timer and a pair of comparators to prevent a load from being re-energized until at least a predetermined period of time has elapsed since the most recent deenergization of the load. A feedback element, such as a zener diode, connected between the output of one of the comparators and a feedback input thereof provides reliable latching of the load through zero crossings of the line in A.C. applications without use of a latching capacitor while simultaneously providing brownout protection capable of rapidly deenergizing the load in the event of an undesired decrease in line voltage.

  • Patent number: 4825328
    Abstract: A three phase electrical load protection device is disclosed including an input transducer for detecting each phase voltage and the direction of rotation of the phases of a three phase power system. A control monitor is disclosed for monitoring signals from the input transducer representative of the highest and lowest phase voltages and the direction of rotation of the phases for controlling an output device for disconnecting the electrical load when improper supply conditions are detected and monitored.
