APC Symmetra LX 4kVA Scalable to 8kVA N+1 UPS

Designed for mission-critical environments, the APC Symmetra LX 4kVA Scalable to 8kVA N+1 UPS delivers unmatched business continuity through a modular, redundant architecture that scales power and runtime as demand evolves. Starting at a robust 4 kVA, this system can be expanded to 8 kVA while preserving N+1 availability, enabling IT teams to protect high-density workloads, virtualization platforms, and data center edge deployments without disruptive outages. Its modular design supports hot-swappable power modules and battery packs, so you can increase capacity and extend runtime with minimal downtime. With advanced management features, Symmetra LX provides real-time visibility into power health, load, runtime, and environmental conditions, empowering proactive maintenance and efficient resource planning. Whether you are building a new data center, upgrading an existing IT room, or protecting a critical network backbone, Symmetra LX combines reliability, scalability, and efficiency to keep your business online when it matters most.

• Modular scalability for growing workloads: Start at 4 kVA and scale up to 8 kVA with seamless addition of power modules. This architectural approach lets you match capacity to demand, supports consolidation of IT assets, and minimizes downtime during expansion by enabling live module insertion and removal without interrupting power to protected equipment.
• N+1 redundancy for elite availability: An inherently redundant configuration ensures continuous operation even during maintenance or module failure. This design protects critical workloads from power interruptions, preserving SLAs and uptime across data centers, cloud nodes, and edge deployments.
• Fast, non-disruptive maintenance: Hot-swappable power and battery modules allow technicians to upgrade or replace components without powering down connected devices. The modular bays support quick swaps with minimal training, reducing MTTR and preserving business continuity.
• Flexible deployment and management: Choose from rack-mount or tower configurations to fit space constraints, with scalable strings of units in an N+1 stack. Built-in management features, plus optional remote monitoring and integration with APC software, provide real-time visibility into voltage, current, runtime, temperature, and load for proactive protection and capacity planning.
• Proven protection for data center and edge environments: Reliable power conditioning, transient suppression, and clean output protect servers, storage, and networking gear. The Symmetra LX integrates with existing infrastructure to reduce energy use and cooling demand while delivering consistent, high-quality power for mission-critical applications.
