Modular UPS Architecture for Growing Critical Loads
Vertiv Liebert APM2 provides a scalable UPS platform for organizations planning capacity expansion and redundancy within mission-critical power systems. Its high efficiency across different load profiles helps reduce operating costs.
Three-level IGBT topology and Silicon Carbide (SiC) converter technology support high power density and serviceability. The hot-swappable modular architecture helps shorten maintenance and service times.
Key Features of Liebert APM2
Online Efficiency
Helps reduce operating costs through high efficiency across different load profiles.
Unity Power Factor
A unity output power factor of 1.0 enables more effective use of rated capacity for critical loads.
Modular Architecture
Hot-swappable modules simplify capacity expansion, maintenance and servicing.
Parallel Redundancy
Supports up to six units in parallel for capacity expansion and N+1 redundancy strategies.
Ideal Applications
Modular UPS Infrastructure for Expanding Data Centers
Vertiv Liebert APM2 is designed for mission-critical facilities that need to plan capacity growth and redundancy within a modular, transformer-free UPS architecture. Its scalable design allows power capacity to be expanded incrementally as project requirements and critical loads grow.
Recommended Applications
Why Choose Liebert APM2?
An efficient, scalable and service-friendly UPS platform for mission-critical power applications.
Efficient Operating Modes
ECO, Dynamic Online and Double Conversion modes optimize efficiency across changing loads.
Scalable Capacity
Modular expansion and parallel operation support changing capacity and redundancy requirements.
Rapid Serviceability
Hot-swappable modules help reduce maintenance time and simplify on-site servicing.
Configuration and Options
Configure the Right Battery Strategy
Liebert APM2 can be configured with VRLA or lithium-ion battery solutions according to project requirements. The appropriate battery architecture is determined by evaluating runtime targets, available space, thermal conditions and maintenance requirements.
Maintain Operational Continuity During Maintenance
Bypass scenarios should be incorporated into the system design to prevent interruptions to critical loads during maintenance and servicing. The APM2 maintenance architecture supports operational continuity throughout planned maintenance windows.
Scale Capacity and Redundancy
Parallel configurations support capacity expansion and system-level redundancy requirements. APM2 provides a flexible architecture for scaling capacity and planning N+1 redundancy as operational requirements grow.
Monitoring and Integration
Liebert APM2 can be configured to support monitoring, alarms and event management. SNMP and Modbus communication enables integration with Data Center Infrastructure Management (DCIM) and Building Management Systems (BMS), improving operational visibility.
