First of all, I'm new to the board. I've used the site a few times to research questions, but have never used it to post. My questions is very simple. What brand of VFD's do you recommend? I consistantly use VFD's for various applications (conveyors, fans, misc machines, etc..). Most of the applications are 20 HP and less and use 480 VAC. Open loop, general purpose VFD's usually fit the bill. I've experimented with many different brands. I've had relatively good luck with all of them, however, I seem to have just as much success with cheap ones as expensive ones. We use a lot of cheap taiwan manufactured Delta (www.deltadrives.com). We've used a lot of Toshibas, Square D's, ABB's, Allan Bradley's, etc etc. My inclination is to continue using the Delta's, but I'm affraid of future consequences. Any opinions you can offer are greatly appreciated.

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
