Abstract
A fuseless power supply regulator circuit is provided for a gate security system. The circuit has sub-circuitry and components to monitor current levels of current from an unregulated power supply and to stop the follow of current into the circuit when the unregulated supply is providing an excessive amount of current and/or the gate security system is drawing an excessive amount of current as a result of a short or otherwise. The sub-circuitry continues to monitor current levels of current coming from the unregulated power supply and when the current levels drop to acceptable levels reopens the main circuit and allows current to flow into the power supply regulation circuit and on into the power supply circuit.
Claims11
A fuseless security system power supply circuit with overload protection comprising:
- a. a current sensor for sensing the levels of current entering a circuit;
- b. a controller that monitors current levels sensed by said current sensor;
- c. a switch responsive to said controller wherein said controller opens said switch to thereby turn off current entering the circuit when a specific current level is sensed;
- and
- d. wherein said controller continues to periodically senses current levels at said current sensor and closes said switch when current levels have fallen below the preset level and thereby allow current to flow into the circuit again.
A method for preventing overload in a security system circuit comprising the steps of:
- a) monitoring current levels of current entering a security system circuit;
- b) shutting the circuit down when the current levels reach a preset level;
- c) continuing to sample the current being supplied for the circuit;
- d) determining when the current levels of the current being supplied to the circuit have fallen below the preset levels;
- e) resetting the circuit to accept current for operation after determining the current levels have fallen below the preset levels;
- and
- f) continuing to monitor the current levels after resetting of the circuit.
