Electric supply circuit for electromechanical lock, has current limiting unit limiting electric current supplied by voltage source when current required by output terminals exceeds predetermined threshold voltage

摘要

The circuit has positive and negative electrical voltage input terminals (26A, 26B) connected to an electrical voltage source. Output terminals (28A, 28B) and electronic output terminals (30A, 30B) are connected to the input terminals. A current limiting unit (40) limits electric current supplied by the voltage source when the current required by the terminals (28A, 28B) exceeds a predetermined threshold voltage. An independent claim is also included for a lock assembly including an electromechanical lock and an electric supply circuit.
