Battery Backups (UPS) Types
Smaller Uninterruptable Power Supplies (UPS) come in 2 basic forms, Line-Interactive and Double Conversion. Line-Interactive systems are cheaper but they do not provide truly instant switching to battery power and could still result in momentary power loss to equipment during an outage.
Line-Interactive vs. Double Conversion – What’s the Difference?
Line-interactive – These UPS systems monitor incoming voltage from the utility. If it detects a power loss or anomaly, it will boost or decrease utility power by allowing it to pass to the protected equipment or by running on battery power.
This model is ideal for applications where the utility power is fairly clean.
Online double-conversion – These UPS systems provide the highest level of protection by isolating the equipment from raw utility power. The system works by converting power from AC to DC and then back to AC.
This unit is the only UPS that provides power with zero transfer time to the battery, making it ideal for sensitive equipment. That’s why it’s the best option for any facility with mission-critical equipment and in locations with poor power conditions.
