Soft start units, as opposed to direct-on-line systems, gradually apply current to the motor at start up.
These units are simple pieces of kit, compared to inverters, tailored to do a very specific function. As such you have to be accurate when selecting a device, this datasheet may help.
You'll need to consider a number of factors to ensure you get a unit that will not only do the job, but also be the most cost-effective solution.
Application, frequency of starts, connection and current rating all determine what you need. If you are unsure please contact us.
