AC, DC, and VFD Drives

IronHorse® GSD Series DC Drives - 1/50 HP to 3 HP
These IronHorse DC drives can accommodate 1/50 hp @ 12VDC all the way up to 3hp @ 240VAC. DC motors and drives can provide several advantages and benefits over AC:

Inexpensive
Low speed performance
Low speed power
Simple
- our DC drives typically use potentiometers for configuration
- no parameters or programming needed
DC Drives Overview and Selection Guide

Variable Frequency AC Drives - 1/4 HP to 100 HP
AutomationDirect carries a range of AC variable frequency drives (VFD) for motor speed control and other industrial control applications.

The high quality and low prices make our GS1 series mini AC drives and GS2 series micro variable speed drives an incredible deal.
The DURApulse (GS3 series) sensorless vector AC drives can handle applications from 1 horsepower up to 100 horsepower.
Single phase only, dual single / three phase, and three phase only AC drives are available.
