Making stationary engines more efficient when loads are reduced
You're welcome, Once they are setup its pretty much pushbutton start. To be fair the same thing can be done with a vfd, it just takes some more setup. Sent from my SM-G973U using Tapatalk- Scoobyshep

Making stationary engines more efficient when loads are reduced
A vfd (variable frequency drive) takes ac inverts it to dc than through a set of transistors created a pulse width modulated synthetic ac output at a user specified frequency. This allows motors to be started slowly and run at different speeds. A soft start is basically a smaller dumber...- Scoobyshep

Making stationary engines more efficient when loads are reduced
The last time I had to look into it (approx 2 years ago) it was cheaper to soft start. But you never know you might get the deal of a lifetime. You also have to make sure the motor is rated to operate with a vfd, some of them dont work well with the carrier frequency (burnt windings is a smell...- Scoobyshep

If you are not changing the electric motor speed you are better off using a soft start vs vfd. Sent from my SM-G973U using Tapatalk- Scoobyshep
