IronHorse GSD1 series DC drives from AutomationDirect (Cumming, GA) are Pulse-Width-Modulated (PWM) controllers for 12- to 36-Volt battery/solar-powered equipment. Design features include adjustable maximum/minimum speed, current limit, I.R. compensation, and acceleration. The adjustable current-limit feature protects the control, battery, and motor from sustained overloads. The drives, available up to 1/4 hp, are available in open-frame and NEMA 4X enclosed styles, and all come standard with a speed pot, knob, and dial plate; an optional 0-10VDC analog input signal card is also available.
GSD3 drives are general-purpose, variable-speed controllers for small DC and universal motor applications up to 1/3 hp. GSD4 drives are offered in dual-voltage 120/240 VAC or 24/36 VAC models, and installation and field adjustments are made using a barrier-type terminal strip and large adjustable trim pots to adjust horsepower ranges. They feature an inhibit circuit for start-stop operation, and 1% speed regulation over a 50:1 speed range.
