The GSD6 series is the most fully-featured IronHorse analog DC drive. It provides many standard features typically offered as options from other manufacturers' by combining advanced engineering design, quality component selection, and rigorous quality control.
GSD6 Series DC drives start at
1/50 - 1 HP @ 120 VAC input; 1/25 - 2 HP @ 240 VAC input
Instant reversing, quick stopping, rapid cycling ... The IronHorse GSD7 series DC drives outperform other dynamic braking and reversing drives by utilizing unique zero-speed detect and dynamic braking circuits. These circuits eliminate contact arcing and failed braking problems and eliminate motor plug reversing problems. In the event of a power loss or emergency stop condition, the GSD7 Series DC drives will drop into a dynamic brake condition.
GSD7 Series DC drives start at
1/2 - 1 HP @ 120 VAC input; 1 - 2 HP @ 240 VAC input
The GSD8 series DC drives are compact, microprocessor-based motor controllers capable of factory or field configurations for a variety of industrial applications. GSD8 DC drives make use of either a pulse accumulation algorithm (GDS8-240-5C) or a velocity PID algorithm (all other GSD8 drives) that can be easily configured for operation as a speed controller, time-based process controller, or follower drive in a master-follower application.
