Direct current drives are PWM controllers with current limit feature

AutomationDirect IronHorse line of motors and drives now includes the GSD series of dc drives.

12/30/2013


AutomationDirect IronHorse GSD1 series dc drives are high-efficiency pulse-width-modulated (PWM) controllers for 12 V to 36 V battery and solar-powered equipment. The design features include adjustable maximum and minimum speed, current limit, I.R. compensation, and acceleration. The adjustable current-limit feature protects the control, battery, and motor from sustained overloads.

Courtesy of AutomationDirectThe GSD1 series dc drives are available up to ¼ hp and are available in open-frame and NEMA 4X enclosed styles. Each comes standard with a speed pot, knob, and dial plate, and an optional 0-10 V dc analog input signal card also is available.

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

The drives, offered in dual voltage 120/240 V ac or 24/36 V ac models, 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, easily adjustable trim pots to adjust horsepower ranges. The GSD4 series drives feature an inhibit circuit for start-stop operation, and 1% speed regulation in a 50:1 speed range.

The GSD5 series is rated to 2 hp and has a dual input voltage (120/240 V ac and 50/60 Hz). The GSD5 series drives are offered in open-frame and NEMA 4/12 enclosed models.

The GSD6 dc drive is an analog dc drive with a feature dual input voltage (120/240 V ac 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, and dc tachometer feedback.

The GSD7 series dc drives are available up to 2 hp. They are designed for instant reversing, quick stopping, and rapid cycling to outperform other dynamic braking and reversing drives by using zero-speed detection and dynamic braking circuits. The zero-speed detect circuit can eliminate motor plug reversing problems and additional features include 0.5-second fixed acceleration, automatic dynamic braking on power loss, and line voltage compensation.

The GSD series dc drives come with a one-year warranty. Additional accessories such as speed potentiometer kit, analog current and voltage input cards, digital potentiometer, and manual reverse switch are available.
