Don't Let Voltage Sags Bring You Down

What is a voltage sage? As defined by IEEE, it is a reduction in voltage below 90% of nominal for a short time. Sags are caused by faults on the power provider’s transmission or distribution lines and can cause equipment error codes and malfunction. They draw abnormally large amounts of current when the voltage recovers that can trip electrical circuits causing downtime and lost productivity.

  • Power dip protection supplements AC voltage during a sag event
  • Restores voltage within 2 milliseconds
  • Handles sags over a greater range than a standard voltage regulator
  • Protects sensitive equipment and environments
Models: SE-15, SE-20

    The ESP Sag Eliminator's power dip protection mitigates AC line voltage sags by supplementing the voltage available during a sag event to give continuous power to the load. Its patented technology typically restores voltage to above 90% of nominal within 2 milliseconds, considerably faster over a greater range than a standard voltage regulator.

    Voltage sags are a drag on your business. Ensure equipment continues to receive stable power and can function normally with ESP's Sag Eliminator.
