The VariSpeed 240 series is a family of DC motor speed controls for industrial applications operating at 240 volts. These units regulate the speed of DC motors in the fractional-to-integral horsepower range, from 1/8 HP up to 5 HP, by providing adjustable voltage output to the motor armature.
The series includes both complete motor control units and individual motor control boards, supplied primarily under the Hampton Products and Danfoss names, with related products from Graham, Graham Transmissions, and Raymond Corporation. Products carry designations across the 700-series and 1800-series part numbers.
Applications
VariSpeed 240 controls are used in industrial automation and machinery that requires variable motor speed, including material handling systems, packaging machinery, and conveyor applications. Many units feature front panel controls and display for operator interface.
