EMX4 Low Voltage Soft Starter
The EMX4i Soft Starter sets a new standard for soft start technology. Not only is the EMX4i smaller, more powerful, and equipped with new control and protection features, but it also introduces game-changing Smart Card capabilities. Attaching a Smart Card to the EMX4i transforms it from a super smart motor controller to a complete system controller.
