A voltage sag, as defined by IEEE, 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 ESP's Sag Eliminator 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.
For over 30 years, leading technology companys have relied upon ESP surge protectors to safeguard their equipment from disruptive and catastrophic power disturbances.
