All Eaton DS7 soft starters incorporate the firm's patented asymmetrical trigger control technology, which eliminates the direct current components in the motor current that are produced by conventional two-phase controlled soft starters. This means the motor starts more smoothly and with less vibration, minimising start-up times. The performance of DS7 soft starters is therefore fully comparable to that of bulkier and more costly three-phase controlled soft starters.
Eaton's DS7 soft starters are an alternative to conventional star-delta starters in a wide range of applications, such as pumps, where their ability to eliminate water hammer reduces wear on the whole installation; fans, where they reduce wear on drive systems; and conveyors, where smooth starting and vibration-free operation minimises equipment wear and the risk of product damage.
