Uninterruptible power supply

The Liebert APM from Emerson Network Power is a row-based, modular uninterruptible power supply that can operate without transformers.


Emerson Network Power introduced the Liebert APM row-based, modular uninterruptible power supply (UPS) system. The product is a transformer-free, on-line UPS that allows quick power capacity increases with the addition of internal FlexPower core hardware assemblies. The FlexPower core assemblies allow the system to expand for capacity or redundancy in 15 kW increments up to 45 or 90kW within a single cabinet. In both models, the external battery cabinet can be outfitted with the Alber BDSi monitoring system to constantly monitor each battery, ensuring battery reliability and allowing for proactive management. Addition or replacement of FlexPower cores can be accomplished without powering down connected equipment.
