A three-phase or other rheostat is a device which is used to control the current flow in a three-phased electrical power system. It acts like a dimmer switch on a light, only for a vastly larger and more powerful machine. This machine is crucial in certain industries where devices require varying amounts of power at different times. Our organization, Yousi, manufactures superior-quality three-phase variable resistors that enable industries to operate more efficiently and safely.
Yousi sells these three-phase rheostats, super efficient. They regulate precisely how much electricity passes through them to get large machines to work perfectly. That way, the machines don’t consume more power than they have to — which can add up to big energy and financial savings. These are very good knobs for factories that have big machines that make things like cars and clothes, or food.

The Yousi three-rhenostat phase is durable. We use durable materials that can support rugged conditions in industrial plants. That said, once you have installed one of our rheostats, you can count on it working well for a very long time. This is a boon for factories, which don’t have to fret about swapping them out so frequently or dishing out the cash to do so.

It is the same for every factory and they maybe need a kind of three-phase rheostat. Yousi recognizes this, and that is why we have custom products. A rahostat that is just what your plant needs — more current, less current, or something else. This is wonderful and all so that you don’t have to re-plumb an entire system to squeeze a new part in.

It can be difficult to attempt to find or install a three-phase rheostat. Not to worry, Yousi is here for you! We've got a crew of specialists to help you learn more about our products. They can assist you in selecting the correct rheostat and even in its installation in your factory. This service can be very helpful for factories, especially if they are installing a new system, or upgrading an old one.
