APC Symmetra LX Extended Run (XR) Tower UPS Models

The SYPM4KP (208/240V) and SYPM4KI (230V) are the technical “engines” of the Symmetra ecosystem.

• Capacity: Each module provides 4kVA of power.
• Hot-Swappability: Allows for live system upgrades and reduces MTTR to minutes, as modules can be swapped without powering down the UPS.
• Intelligence: Includes on-board logic that communicates with the system’s Intelligence Modules for automated load balancing and status reporting.

SYA8K16PXR / SYA8K16IXR

• Analysis: Provides 8kVA capacity with a significantly expanded battery reservoir.
• Floor Loading Insight: At 473.7 kg, these units require a verified floor loading capacity of at least 1500 kg/m² to ensure structural safety.

SYA12K16PXR / SYA12K16IXR

• Analysis: 12kVA scalable capacity with 488.7 kg chassis weight.
• Runtime Strategy: Adding SYAXR9B9I frames shifts the runtime from Curve A (baseline) to Curve E, providing over 100 minutes of protection even at significant loads.

SYA16K16PXR / SYA16K16IXR

• Analysis: The maximum energy storage tower.
• Technical Data: 503.6 kg; 11.2 kW max power; 3707 BTU/hr.

Analyzing Runtime Strategy

The Symmetra LX uses specific run-time curves (A-E) to define energy endurance. By adding SYAXR9B9I frames, the relationship between load (Watts) and runtime (Minutes) is fundamentally altered. For example, at 100% load (11.2 kW), the addition of modular XR frames can extend uptime from minutes to over an hour, flattening the curve and providing the necessary buffer for generator synchronization or graceful system shutdown.
