Liebert

Liebert is primarily a brand associated with Liebert Corporation, a manufacturer of power protection and environmental-control equipment for critical facilities. The Liebert brand is best known for data center infrastructure products, including uninterruptible power supplies (UPS), power distribution units (PDUs), and precision cooling systems. These offerings are designed to protect and manage the operational reliability and energy efficiency of IT environments, telecom facilities, and other mission-critical spaces.

Historically, Liebert Corporation emerged as a supplier of environmental controls for electronics and related industries, expanding into data center infrastructure as demand for reliable power and cooling grew. In the late 20th century, Liebert became part of Emerson Electric Co. In 2016, Emerson spun off its Network Power business as Vertiv, and Liebert became a brand within Vertiv. Today, Liebert-branded solutions are marketed globally for air conditioning and cooling management, power protection, and monitoring services in data centers, cloud facilities, telecommunications, healthcare, and other industries requiring high availability and efficient operations.

In sum, Liebert denotes a foundational brand in data center infrastructure, spanning UPS, PDUs, and precision cooling products, under the corporate umbrella of Vertiv.
