The GS4 Variable Frequency Drive: Your Best Choice for Low Cost VFD

GS4 Drives are available up to 300 horse power in the 460 volt model and 100 horse power in the 230 volt model … AND, all of the 230 volt models run on three phase OR single phase! The keypad entry is super easy to use and even has a “quick start” menu structure designed in simple logical steps to make it easy for you to get up and running quickly. Every drive has a built-in PLC so you don’t need to spend more money on a controller for those times when you need some extra control logic. Software for both the drive and the PLC are available on CD or as a free download from the AutomationDirect website. And the firmware for the Drive & PLC, along with Keypad, & Communications cards are field upgradeable via USB! STO is built-in to these drives so you don’t need to spend extra money on external contactor parts, wiring, cabinet space or spares inventory. Each drive has RS-485 communications built in and can be upgraded to Modbus TCP or EtherNet I/P with optional expansion modules so now you don’t need expensive external boxes to change how you talk to the drive. There’s even modules available so you can customize your I/O to fit your exact needs and those I/O are accessible by either the drive or the PLC! Each Drive has a 100 thousand amp Short Circuit Current Rating, 50 degree C temperature rating, has a Fire Mode, Fan and Pump mode and speaks MODBUS RTU and BACnet which makes it ideal for HVAC applications. And the built in multi motor control modes are great for controlling varying loads like staged pumping applications and for cycling through the motors for balancing the wear on all of the motors in the system. GS4 Drives with fames A through F are flange mountable so the heat sink is outside the cabinet. That can improve the efficiency of the drive and lower the internal temperature of the enclosure which means you might be able to eliminate the need for cooling which saves you money. Speaking of money, if you do a side by side comparison between the GS3 drives and the GS4 drives, you’ll see they are very similar in price. BUT, because the GS4 drives have a wider horsepower range in both three and single phase, and have a lot more built in features that save you money, they are a much better value. So with Tons of free tutorial videos, FREE software, a built in PLC, lots of features that come STANDARD with the drives, free shipping on orders over $49, free tech support, a 30 day money back guarantee, you have nothing to lose.
