Deep Sag Correction Up to 2 Seconds

Bonitron Sag UPD (Uninterruptible Power for Drives) Solutions are the cost effective way to make sure your critical process never sees power disturbances from voltage sags. While some applications experience complete power outages, in most parts of the world sags are the most common culprit of process power disturbances.

Sag Solutions include a voltage regulator that allows your process to continue running at full power during a voltage sag. If future needs require energy storage, a simple add-on can easily be installed.

Bonitron Sag UPD (Uninterruptible Power for Drives) Systems monitor the drive. If the drive voltage sags, the Sag becomes active and provides power to the DC bus. This allows critical processes to never see the disturbance and can continue operating at full power.
