Sag

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 allow 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.

  • No energy storage necessary
  • Provides full-load power for up to 2 seconds for:
    • 50% 3-phase sags
    • 1-phase sag to 0v
 




Bonitron UPD Advantages   In-line UPS Disadvantages

Bonitron UPD Systems power the DC bus of the drive via DC bus connection on the drive. This eliminates an unnecessary and energy wasting DC to AC conversion.

  • Parallel Connection
    • High reliability
    • Seamless power source transfer
  • Increased Efficiency
    • Ultra-low standby power
    • Sized to drive system for reduced cost
    • Power supplied to DC bus for minimal conversions
 

Double conversion UPS systems convert DC voltage that is stored in batteries or capacitors back to AC voltage in order to power the drive, which in turn converts it back to DC. Variable frequency drives are not recommended for use with UPS systems, as the drive input reactance interacts negatively with UPS systems.

  • Series Connection
    • Decreased reliability
  • Decreased Efficiency
    • Unneccesary conversions
    • Converts energy storage back to AC

S3534SR
2-Second Sag
Up to 85A

S3460SR
2-Second Sag
Up to 610A

 

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.
