pointDynamic Sag Correctors




Rockwell/SoftSwitching DySC® Voltage Sag Protectors protect against voltage sags and momentary outages that account for a significant amount of manufacturing downtime and damaged equipment. These DySC® protectors do not require batteries, they have no moving parts, and they require minimal maintenance. They are ideal for manufacturing processes and sensitive electronics that require sag ride-through protection up to five seconds.

No matter the size, scope or focus of your industry, there are three types Rockwell DySC® to help minimize unscheduled downtime, maximize MTBF and maintain your efficiency and bottom line.

SoftSwitching DySC® features:

  • 100% sag protection up to 5 seconds
  • SEMI F47 compliance
