Dynamatic® DSI-700 Controls

Simple yet versatile adjustable speed control, ideal for replacing obsolete and Torspec® Model 5001 controls

The Dynamatic® DSI-700 is an analog, high-quality, high-performance, universal Eddy Current drive controller. DSI-700 has been designed to provide excitation for Dynamatic®, Torspec®, US Motor/Emerson and WER brand Eddy Current drives as well as replace many existing older and obsolete Eddy Current Drive controllers manufactured by others, including an identical drop-in footprint for the Torspec Model 5001 control.

The DSI-700 provides 5.5 amps DC maximum output with adjustable and selectable output voltages from 45 to 180 VDC. The DSI-700 may be used with drives ranging from the Fractional Horsepower (FAS) of drives from 1⁄4 to 1-1⁄2 HP, to the complete Ajusto-Spede® AS brand of integral motor-clutch drives from 1- through 40 HP, as well as the full line of Ajusto-Spede® AT brand drives up to 200 HP. These controllers also provide excellent sources for the Eddy Current Brake series such as the Dynamatic® AS-700 brakes.

The DSI-700 is offered in an Original Equipment Manufacturers’ (OEM) package as a basic, central control unit to provide maximum performance at the lowest possible price. It features single circuit board construction with integral heat dissipater for the power components. Only the topside of the circuit board is populated, using hybrid surface-mount as well as through-hole technologies. The controller board is conformably coated to protect components from damage in harsh environments. The controller may be mounted to a substrate panel using four (4) standoff insulators and mounting screws, provided in a plastic pouch. This allows for easy Integration into larger systems with the addition of the appropriate supporting controls such as starters, switches, and interlocks, on/off controls as required.
