| titleOfInvention | Coil Driving Device of Magnetic Contactor |
| abstract | The present invention relates to a coil driving device of a magnetic contactor, and conventionally, there is a problem in that malfunction occurs due to an error between the establishment time of the electrostatic source and the establishment time of the divided power source in the initial stage of voltage application. Accordingly, the present invention provides a coil drive device of a magnetic contactor, wherein the voltage detector includes: a fifth op amp configured to output a signal by applying a constant voltage to an inverting terminal, distributing the constant voltage to a non-inverting terminal, and amplifying and amplifying the signal; A first op amp that combines the output signal of the fifth op amp and the divided voltage and distributes the sum signal to a non-inverting terminal and distributes the constant voltage to the inverting terminal. It is an object of the present invention to provide a coil driving device of a magnetic contactor which is configured to prevent the generation of a holding current due to a malfunction by operating a circuit after an electrostatic source is properly established. |
