AutomationDirect’s IronHorse GSD series DC drives are built for universal motor applications up to 1/3 hp

AutomationDirect’s IronHorse line of motors and drives includes the GSD series of DC drives. IronHorse GSD1 series DC drives are built to be high-performance Pulse-Width-Modulated (PWM) controllers for 12 to 36 volt battery/solar-powered equipment. Design features are made to include adjustable maximum/minimum speed, current limit, I.R. compensation, and acceleration. The adjustable current-limit feature is made to protect the control, battery, and motor from sustained overloads. GSD1 series DC drives, available up to ¼ hp, are designed to be available in open-frame and NEMA 4X enclosed styles, and made to come standard with a speed pot, knob, and dial plate; an optional 0-10VDC analog input signal card is also available.

IronHorse GSD3 series drives are constructed to be general-purpose, economical variable speed controllers for DC and universal motor applications up to 1/3 hp. Open-frame and NEMA 4 enclosed models are built to be available with dual input voltages (12/24 VAC or 120/240 VAC) with a DC output current rating of 2 Amps, adjustable trim pot settings, and quick-connect terminal pins.

GSD4 series drives are designed to provide reliable control for permanent magnet, shunt-wound, and universal motors up to 2 hp. The drives, offered in dual voltage 120/240 VAC or 24/36 VAC models, are made to incorporate up-to-date design and engineering in a compact package. Installation and field adjustments are facilitated using a barrier type terminal strip and large, adjustable trim pots to adjust horsepower ranges. GSD4 series drives are built to feature an inhibit circuit for start-stop operation, and 1% speed regulation over a 50:1 speed range.

This general purpose, economical line of drives, rated to 2 hp, is made to provide the ultimate in standard features and versatility. With dual input voltage (120/240 VAC and 50/60Hz), GSD5 series drives are made to be offered in open-frame and NEMA 4/12 enclosed models.

An excellent off-the-shelf control device, the GSD6 series drives are designed to feature dual input voltage (120/240 VAC and 50/60 Hz) via slide selector, adjustable horsepower settings up to 3 hp, full-wave bridge supply, 50:1 speed range, transient voltage protection, DC tachometer feedback, and more.

The IronHorse GSD7 series DC drives, available up to 2 hp, are designed for instant reversing, quick stopping, and rapid cycling to outperform other dynamic braking and reversing drives by utilizing unique zero-speed detection and dynamic braking circuits; the zero-speed detect circuit also are made to eliminate motor plug reversing problems; additional features are constructed to include 0.5-second fixed acceleration, automatic dynamic braking on power loss, line voltage compensation, and more.
