Soft start & protect any AC motor

Motor and starter protection is taken to a new level by combining a high-end motor protection relay with a heavy duty solid state starter. Flexible control features and selectable ramping profiles to match any application… no need to compromise performance. High level circuit isolation via fiber optics (standard on all units) for safety and power quality immunity. Sealed NEMA 12 enclosures are standard equipment, not an expensive option.

The MVC Plus Series starter is designed to start AC motors in any fixed speed application. It provides maximum protection with “True Thermal Modeling,” while allowing smooth, stepless control of acceleration and deceleration. The MVC Plus Series guarantees power control and protection for your most important assets.

Heavy-duty attitude highest rated power devices for maximum current carrying capacity. Rated at 500% for 60 seconds, the MVC Plus Series starter will never be the limiting factor in your application. Powerful sustained gate pulse insures reliable SCR firing without reactors (unlike “wimpy” pulse train designs that require a reactor to prevent SCR and motor damage) .
