Liebert APM 30-300kW


Liebert APM 30-300kW
The Compact Row-Based UPS With Flexpower Technology™


Liebert APM is the next generation UPS solution based on the scalable power platforms developed by Emerson Network Power. What differentiates Liebert APM from other power protection solutions is its Adaptive Power Manager features.

Unique in its class, the Liebert APM provides complete high efficient power protection and distribution in a single cabinet, eliminating the complexity of two-stage power distribution. Its intelligent and adaptive capability to manage power within the data center row makes it a suitable solution for business expansion in the future .It features FlexPower technology, which incorporates distributed intelligence and scalable power in a common assembly.

It is suitable for small and medium businesses with the attitude to grow fast: thanks to its architecture that enables the UPS system capacity to start as low as 30kW which can grow with the business up to 600kW.
