The first feature that modern contactors offer is a wide-range electronic, universal coil. Traditionally, contactors had a coil that was for either AC or DC power.
In order to design a panel, you would need to search through a multitude of part numbers of a product to find the coil that fit your application’s specific needs. For every contactor needed, you would need to spend valuable time to examine numerous coils with different AC or DC offerings, hertz ranges, and voltage ranges.
Now, modern contactors have moved away from using traditional coils that were either for AC or DC operation. New, wide-range electronic, universal coils have both AC and DC power capabilities in one coil. These coils are also capable of handling larger voltage ranges.
This means that one new coil in modern contactors can cover the power and voltage ranges of numerous traditional coils. Instead of searching through a multitude of part numbers to find the product that fits your specification, you only need to look at a few options that cover the traditional options, saving design time and cost of labor.
Not only do the new coils reduce part numbers, they also have lower coil consumption than traditional coils. In fact, modern contactors can have an average of 40% reduction in power requirements compared to legacy contactors. Over time, and especially with numerous contactors, this can result in large cost savings in power.
