  • Patent number: 10862299
    Abstract: An electrical protection device used in a controller of a mechanical equipment is disclosed to include a circuit board, and a pre-stage protection circuit and a post-stage protection circuit formed on the circuit board. The pre-stage protection circuit connects a power supply and a pre-stage of the controller, providing an electrical protection condition such that when a transient surge energy of the power supply surpasses the electrical protection condition, the pre-stage protection circuit blocks the transient surge energy from entering the controller. The post-stage protection circuit connects pre-stage protection circuit and a post-stage of the controller. Further, when the transient surge energy occurs, a response speed of the post-stage protection circuit is slower than that of the pre-stage protection circuit.
