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.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
