Overview
The Dart Controls 530BRE is an analog DC motor speed control for motors from 1/8HP to 3HP, delivered in a NEMA 4 enclosed package. Rated to 3 horsepower, it provides many standard features typically offered as options. The 530B Series is designed for Permanent Magnet, Shunt Wound, and some Universal Series (AC/DC) motors, making it well-suited for conveyors, pumps, fans, and general industrial speed control applications.
Key Features
