High Double-Conversion Efficiency
Double-conversion operation reaches up to 97% efficiency with a relatively flat efficiency curve across operating loads.
Vertiv Liebert APM Plus is a high-density, transformer-free modular UPS designed for mission-critical data centres, telecom infrastructure and other demanding applications. Scalable from 50 to 500 kW in 50 kW increments, it combines up to 97% double-conversion efficiency, hot-swappable modules, intelligent controls and compact row-or-room deployment.
Vertiv Liebert APM Plus is a three-phase, transformer-free modular UPS designed to provide conditioned power to medium and large-scale mission-critical infrastructure.
The architecture starts at 50 kW and scales in 50 kW increments. Vertiv offers 50–250 kW and 50–500 kW cabinet frames, with a single system reaching a maximum capacity of 500 kW.
FlexPower technology combines modular power capacity with independent DSP control at module level, enabling the system to regulate operation while retaining a scalable architecture.
In double-conversion mode, the UPS provides efficiency up to 97%. Eco Mode provides efficiency greater than 99%, while current Vertiv documentation separately identifies Dynamic Online Mode with efficiency up to 98.8%.
High-density 3U power modules allow significant power capacity to be integrated into a compact cabinet footprint suitable for both row and room applications.
Power modules and the bypass module use a hot-swappable architecture, supporting reduced replacement time for applicable modular components.
Robust internal airflow directs heated air towards heat sinks while conformal coating on PCBs provides additional protection against environmental conditions and corrosion.
The system operates without capacity impact at ambient temperatures up to 40°C and can continue operating at temperatures up to 50°C with automatic derating.
The Liebert APM Plus combines modular high-density power conversion with efficiency, hot-swappable architecture and advanced digital control.
Double-conversion operation reaches up to 97% efficiency with a relatively flat efficiency curve across operating loads.
Capacity can be increased in 50 kW increments, with independent module-level DSP controls supporting scalable operation.
Power modules and bypass-module architecture support hot swapping of applicable critical modular components.
Independent digital controls within the modular architecture help regulate individual power modules and overall system operation.
Dedicated internal air channels and conformal-coated PCBs support operation in demanding critical-power environments.
A multilingual touchscreen provides operating information, alarms, measurements, battery status and UPS control functions.
Vertiv Liebert APM Plus combines online double-conversion protection with modular FlexPower architecture and advanced digital control for scalable critical-power environments.
The APM Plus platform combines 50 kW modular expansion with multiple efficiency modes, battery configurations, intelligent controls and system-paralleling capability.
Cabinet dimensions, weight, battery configuration, short-circuit options and system architecture vary between the 250 kW and 500 kW frames and the selected configuration.
Key information about capacity, efficiency, modular architecture and configuration-dependent parameters.
Vertiv Liebert APM Plus is a modular, high-density, transformer-free three-phase UPS designed for mission-critical applications, with single-unit capacity from 50 to 500 kW.
