The row-based Liebert APM is a transformer-free, on-line uninterruptible power supply (UPS) that allows quick and easy capacity increases with modular scalability--with no additional floorspace required. Liebert APM operates with the industry's highest data center power efficiency--up to 94% at loads of 50-100%.
The 208 Volt, three-phase Liebert APM is available in two models, expandable with modular power scalability:
- Liebert APM 45kW frame size is expandable from 15 to 45kW, with up to 45kW of capacity, or up to 30kW of capacity with a 15kW module for redundancy. This frame size includes internal batteries, and is compatible with the matching external battery cabinet and the optional Liebert APM bypass distribution cabinet (BDC).
- Liebert APM 90kW frame size is expandable from 15 to 90kW, with up to 90kW of capacity, or up to 75kW of capacity with a 15kW module for redundancy. This frame size requires the matching external battery cabinet, and is compatible with the optional Liebert APM BDC bypass distribution cabinet.
