Review on Optimize Energy Usage with HUANYANG Variable Frequency Inverter Converter by Todd Look

Very good VFD controller, number of adjustable parameters is impressive and a little bit impressive. I particularly like the ability to set precise values for maximum voltage and current, as well as the time it takes for the speed to increase to reach the RPM target. The latter means you can control very heavy motors/equipment that would otherwise immediately overload the controller, as well as prevent the motor from accelerating too quickly when setting the speed with the front stick. It would be nice to have a more detailed display as it only shows one value at a time (default is RPM), voltage and current draw would be very helpful. FYI, the application I am using this controller for is controlling a 24V turbomolecular pump. The blade unit is very heavy and the current limiting kicks in without very slow acceleration, so with the right settings it works very well with this controller.
