The modular keypad is cool...manual not so good.
I bought this one, and have it installed and it runs just fine. The manual? Well I wanted an external simple 2 wire on off switch, but could not find what terminal connections to use. I flailed for a while and then gave up when I realized the digital keypad could be pulled entirely and installed that where I wanted the switch...I am waiting for the ribbon cable 2x5 to span the distance. I realized the modular nature of the digital keypad is a big plus...I want to order a spare to have it when the day comes that the keypod contacts wear out...I can't find that on their web site so I wrote to them to see if I can get one.

Works Good
This application is for speed control of a pump. pretty straightforward install. The terminals were in an awkward position but still accessible with some patience. Would have liked to have a reversing switch but had a work around. Good unit for the price.

Power convert made easy
Easy set up , two phase to three phase easily done , no need to do crazy configuration. Recommend to anyone who need to run a three phase machine(commercial power supply) at a residential setting which is only two phase,.

VFD Solves Wiring Issue
We purchased and installed these VFDs because we did not have 220Volt power at the location. They are controlling the speed of our incline conveyors. They solved our issue elegantly. These are cost-effective and a digital electronic solution vs a less efficient analog option.

Très bon service à la clientèle, même si l'appareil a pris du retard à la douane, j'ai été assisté. On m'a remboursé les frais d'importation que j'ai payés à la douane. Pour le moment je n'ai utilisé le variateur. Lorsque je le ferai, je donnerai mon évaluation complète.
