When I started in the trade, I would see these devices (above) in the field, and I would hear guys call them a PTC or a soft start, and I just accepted it and moved on. To get the data we need to design systems that mitigate those issues, we need to do a blower door test. How It Helps. Just to add some more info, an SCR is a 4-layer PNPN device that can be equivalently thought of as a PNP and an NPN transistor connected to provide positive feedback. It connects from run to start in parallel with the run capacitor and allows a surge of current to travel to the start winding of a motor when it starts. It increases in-rush to the compressor and doesnt provide any protective benefits. A conventional starter may generate enough pressure at startup to break the line. It is the electronic switch used to facilitate things like soft starts. The linked speed controller clearly states that it is for a universal motor and only a universal motor.
