Emerson 210120019206 US11R 0010L UPS system module for Liebert power protection infrastructure.
The Emerson 210120019206 is a US11R 0010L module designed for use within Emerson’s Liebert uninterruptible power supply systems. This component forms part of the power protection infrastructure used to maintain continuous, clean power delivery to critical network and telecommunications equipment.
Liebert UPS systems are widely deployed in data centres, telecommunications facilities, and enterprise server rooms where power reliability is essential. The US11R series modules provide power conditioning and backup functionality to protect sensitive electronic equipment from power disturbances, outages, and fluctuations.
As Emerson’s power division transitioned to Vertiv in 2016, many Liebert product lines have been rebranded or superseded. However, the 210120019206 remains relevant for organisations maintaining existing Liebert UPS installations and seeking compatible replacement or expansion modules.
