Overview

The Dart Controls ASP10 is a closed-loop digital speed potentiometer designed for precise motor speed control in continuous applications. This panel-mount unit offers an LED display of set speeds, allowing for direct readouts in engineering units such as RPM, FPM, GPM, or process time. Its on-board microprocessor and sophisticated software ensure exceptional accuracy and repeatability, controlling speed to within 0.5 RPM of the setpoint long-term. The ASP10 is compatible with conventional AC, DC, or Brushless DC adjustable speed drive systems that accept a 3-wire speed pot input. Field programming via friendly front-panel pushbuttons allows customization of maximum and minimum set speeds, decimal point/colon display, operating mode (master or follower), and motor gear ratio constants. In follower mode, multiple motors can operate at speeds proportional to each other, ideal for blending or synchronized material handling. The ASP10 features a rugged screw-type terminal strip for easy wiring and fits industry-standard 1/8 DIN cutout dimensions. It operates on universal supply voltage (120/240 VAC) and is NEMA 4X rated when installed in a similarly rated panel, making it suitable for washdown environments. This unit is an exclusive offering from Dart Controls, providing advanced control capabilities without the need for a separate drive.
