APC Symmetra 3 Battery Rackmount XR Frame (208/120V Regions) - SYBFXR3RM

APC by Schneider Electric SYBFXR3RM Symmetra 3 Battery Rackmount XR Frame

Overview

The APC by Schneider Electric SYBFXR3RM is a 5U rackmount extended-runtime battery frame designed for the Symmetra 3-phase UPS platform serving 208/120V regions. Where a base Symmetra cabinet covers standard runtime requirements, this XR frame lets you bolt additional VRLA battery capacity directly into the rack — extending ride-through time for critical loads without deploying a separate floor-standing unit. At 472 × 686 × 215 mm and a packaged weight of 30.9 kg, it occupies five rack units and fits standard 19-inch EIA cabinets. For data centers, network operations centers, and industrial control rooms that need runtime headroom beyond what the base UPS cabinet provides, the SYBFXR3RM is the scaling path APC designed into the Symmetra architecture from the start.

This is a power and UPS expansion module — not a standalone UPS. It pairs with the Symmetra 3-phase UPS frame and requires compatible battery modules to populate the frame. Plan your battery module count and runtime targets before ordering. Consult the APC by Schneider Electric catalog for the full Symmetra family and compatible battery module SKUs.

Key Features

• 5U Rackmount Form Factor: Five rack units of height in a 472 × 686 mm (W × D) footprint integrates cleanly into standard 19-inch racks without demanding floor space — a direct advantage in dense data center rows where every square foot has a cost.
• Sealed Lead Acid (VRLA) Battery Technology: Valve-regulated lead acid chemistry requires no liquid maintenance and can operate in any orientation, reducing the operational overhead associated with wet-cell alternatives. VRLA cells are also the industry standard for UPS extended-runtime applications, which simplifies replacement sourcing.
• 208 V System Voltage: Rated for 208/120V three-phase environments common in North American commercial and industrial facilities. Confirm your Symmetra UPS frame matches this voltage configuration — the XR frame is not cross-compatible with 400V international variants.
• 0–40°C Operating Temperature: Covers the thermal range of most air-conditioned server rooms and light-industrial enclosures. The 45°C upper storage limit is equally practical — batteries stored in unconditioned warehouses during staged rollouts won't be thermally stressed.
• 0–95% Relative Humidity (Non-Condensing) Operating Range: Broad humidity tolerance means the frame can be deployed in facilities with less-than-ideal HVAC control, such as manufacturing plant MER rooms, without triggering battery management concerns.
• 0–3000 m Operating Altitude: Covers virtually all terrestrial deployment sites, including high-altitude data centers and industrial facilities in mountainous regions — no derating calculations required below 3,000 meters.
• CSA and UL 1778 Certification: UL 1778 is the UPS-specific safety standard; CSA covers Canadian market requirements. Both are required for insurance compliance and are frequently a procurement prerequisite in regulated verticals like healthcare and finance. No workarounds needed for North American code inspections.
• Rackmount Extended Runtime Architecture: The XR frame model is purpose-built to daisy-chain with the Symmetra base frame, extending runtime in discrete, measurable increments as battery modules are added. This is a cleaner scaling approach than oversizing the initial UPS purchase for speculative future load.

Integration and Compatibility

The SYBFXR3RM is part of the APC Symmetra 3-phase UPS ecosystem and requires a compatible Symmetra 3-phase base UPS frame. Battery modules are sold separately; the XR frame is an empty chassis at shipment. Verify battery module compatibility with APC's Symmetra product matrix before provisioning — not all Symmetra battery modules are interchangeable across frame generations.

For facilities planning extended runtime for network video recorders, access control servers, or other security infrastructure, this frame integrates with standard rack power distribution units (PDUs) and rack cabinets common in 19-inch EIA environments. APC's EcoStruxure IT software and InfraStruXure monitoring tools are compatible with the broader Symmetra platform for runtime monitoring and predictive battery management. Check current APC documentation for specific software compatibility with your Symmetra frame generation.

For facilities requiring complementary rackmount power distribution or monitoring, explore rackmount UPS and power infrastructure options alongside this frame. An in-house pre-sales engineering review is recommended for runtime calculations — load profiles, battery module count, and discharge curves interact in ways that spreadsheet estimates routinely understate.

Frequently Asked Questions

Q: What UPS does the SYBFXR3RM work with?

A: The SYBFXR3RM is an extended-runtime battery frame for the APC Symmetra 3-phase UPS platform configured for 208/120V regions. It is not a standalone UPS and must be paired with a compatible Symmetra base frame. Verify frame generation compatibility with APC documentation before ordering.

Q: Does the SYBFXR3RM include batteries?

A: No. The SYBFXR3RM ships as an empty chassis. Battery modules are ordered separately and installed into the frame. Consult APC's Symmetra battery module compatibility list to identify the correct modules for your frame and runtime targets.

Q: What rack size does the SYBFXR3RM require?

A: The SYBFXR3RM occupies 5U (five rack units) and measures 472 mm wide × 686 mm deep × 215 mm tall — compatible with standard 19-inch EIA rackmount cabinets. Verify rack depth accommodates the 686 mm frame depth before installation.

Q: What certifications does the SYBFXR3RM carry?

A: The SYBFXR3RM is certified to CSA and UL 1778. UL 1778 is the UPS-specific safety standard required for compliance in most North American regulated environments including healthcare and financial facilities.

Q: Is the SYBFXR3RM suitable for outdoor or high-humidity environments?

A: The operating humidity range is 0–95% (non-condensing) and the operating temperature range is 0–40°C. It is designed for indoor rack enclosures — not outdoor or uncontrolled environments. Condensation must be avoided.

Q: What is the operating altitude limit for the SYBFXR3RM?

A: The SYBFXR3RM is rated for operation up to 3,000 meters above sea level, covering the vast majority of terrestrial commercial and industrial installation sites without derating.

James Everett

The SYBFXR3RM is a straightforward but easy-to-misconfigure component in the Symmetra 3-phase architecture. The frame itself is 5U, 472 mm wide, and 686 mm deep — that depth catches integrators off-guard more often than you'd expect. Before the rack is even ordered, confirm your cabinet's usable interior depth handles the frame plus any rear cable management. I've seen SYBFXR3RM installs stall because the rail kit hit the PDU brackets.

Technical Highlights:

• VRLA Chemistry: Sealed lead acid cells require no liquid maintenance and can be rack-mounted at any orientation — a practical advantage when the XR frame needs to slide into a two-post or four-post open rack without dedicated battery cabinet hardware.
• CSA + UL 1778 Dual Listing: Both certifications are on a single SKU, which simplifies procurement paperwork for projects spanning US and Canadian sites — you're not sourcing a separate SKU for cross-border installs.
• 0–3000 m Altitude Rating: Genuinely useful for high-elevation sites like mountain-region telecom huts or industrial control rooms above 1,500 m where some battery technologies require derating. The SYBFXR3RM operates without adjustment across that full range.

Deployment Considerations:

• The SYBFXR3RM ships empty — no battery modules are included. Runtime calculations must be done against the specific battery modules you order separately, not against the frame. Treat this as a chassis procurement, not a complete battery solution.
• Operating temperature ceiling is 40°C. In facilities where cooling is intermittent or subject to summer peaks, that's a real constraint — VRLA cells degrade faster above 25°C, and the 40°C operating limit doesn't mean optimal performance at that temperature.

For NOCs, financial trading floors, or security operations centers where Symmetra 3-phase is already the backbone UPS platform and incremental runtime extension is the goal, the SYBFXR3RM is the designed-in answer — not a workaround. It's not the right call for greenfield sites where the base UPS hasn't been selected yet; start with the UPS frame first and size battery expansion from there.
