APC Smart-ups RT 48V RM Battery Pack - SURTA48RMXLBP2U

APC by Schneider Electric SURTA48RMXLBP2U 48V Rack-Mount Battery Pack

Overview

The SURTA48RMXLBP2U is a 48V DC, 2U rack-mountable battery pack designed to extend runtime for compatible APC Smart-UPS RT systems. If your facility runs surveillance, access control, or network infrastructure on a Smart-UPS RT 1500VA RM 120V and runtime is a genuine concern — during extended outages or planned maintenance windows — this is the add-on battery unit that buys you more uptime without replacing the UPS itself. At 72.55 lb, it is a dense, purpose-built unit; plan your rack load calculations before ordering.

Key Features

• 48V DC Output: Matches the internal battery bus of compatible Smart-UPS RT models exactly. No voltage conversion loss, no adapter required — the host UPS sees this as a native extension of its own battery string.
• 2U Rack Form Factor: Occupies 2 rack units, keeping your cabinet footprint predictable. If you are already running a 1U or 2U UPS in a 12U or 16U security rack, this fits cleanly in the adjacent slot without requiring a separate enclosure.
• Spill-Proof Lead Acid Chemistry: Valve-regulated lead acid (VRLA) construction means the cells are sealed and can be mounted in any orientation without venting hazardous gases into enclosed rack spaces — a real consideration in comms closets and IDF rooms with limited ventilation.
• 72.55 lb Verified Weight: This is not a light accessory. Factor this into rack rail load ratings and floor load limits, particularly in raised-floor data rooms or mobile rack deployments. Two-person installation is the practical minimum.
• RoHS Compliant: Meets Restriction of Hazardous Substances requirements, supporting procurement compliance in government, healthcare, and EU-market deployments where environmental documentation is required.
• Black Rack Finish: Matches standard rack aesthetics in both open-frame and enclosed cabinets — not a functional spec, but worth noting for installations where mixed-finish racks are a client concern.

Integration & Compatibility

The SURTA48RMXLBP2U is verified compatible with the APC Smart-UPS RT 1500VA RM 120V. Before ordering, confirm your specific host UPS model against APC's compatibility matrix — the RT battery bus architecture is shared across several models, but the connector and battery management interface must match your unit exactly. Do not assume compatibility with non-RT or tower-form Smart-UPS models.

Frequently Asked Questions

Q: Which UPS models is the SURTA48RMXLBP2U compatible with?

A: The SURTA48RMXLBP2U is verified compatible with the APC Smart-UPS RT 1500VA RM 120V. Confirm your specific UPS model against APC's compatibility documentation before purchasing.

Q: How much does the SURTA48RMXLBP2U weigh, and are there special installation requirements?

A: It weighs 72.55 lb. This requires attention to rack rail load ratings and floor capacity. Two-person installation is strongly advisable.

Q: What battery chemistry does the SURTA48RMXLBP2U use?

A: It uses spill-proof, sealed lead acid (VRLA) chemistry, safe for enclosed rack installations without special ventilation requirements.

Q: Is the SURTA48RMXLBP2U RoHS compliant?

A: Yes, it carries RoHS (Restriction of Hazardous Substances) compliance, documented via Schneider Electric's EU RoHS declaration.

Q: Does the SURTA48RMXLBP2U ship with rack mounting hardware?

A: Yes. The package includes rack mounting brackets and a user manual for rack installation.

James Everett

The SURTA48RMXLBP2U is straightforward in purpose but easy to get wrong on the procurement side. At 72.55 lb in a 2U chassis, this is one of the heavier components you will drop into a security or network rack — and the 48V DC output is non-negotiable for the RT bus architecture, so host UPS compatibility must be confirmed before the unit ships.

Technical Highlights:

• 48V DC Native Bus: Connects directly to the Smart-UPS RT battery string with no voltage conversion — runtime extension is clean, with no efficiency penalty introduced by the pack itself.
• Spill-Proof VRLA Chemistry: Sealed cells allow rack mounting in standard enclosed cabinets without ventilation modifications — relevant in IDF closets and compact security headend rooms where airflow is already constrained.
• 2U Rack Profile: Predictable footprint for cabinet planning; pairs cleanly with 1U or 2U UPS hosts in standard 12U–42U rack enclosures common in mid-size commercial security infrastructure.

Deployment Considerations:

• Verify your host UPS model explicitly against APC's RT battery compatibility list — the SURTA48RMXLBP2U is confirmed for the Smart-UPS RT 1500VA RM 120V, but the RT family spans multiple SKUs with different battery interfaces.
• At 72.55 lb, this unit stresses mid-rail and rear-rail load limits on lighter-duty racks; confirm rail ratings and schedule a two-person install — sliding it in solo is a liability issue, not just an inconvenience.

Best fit for commercial security integrators extending runtime on Smart-UPS RT 1500VA RM deployments in access control headends, surveillance NVR closets, or network IDF rooms where a single extended outage justifies the added battery capacity.
