APC by Schneider Electric SRT192RMBPM Rack-Mount Extended Battery Cabinet
Overview
The APC by Schneider Electric SRT192RMBPM is a 192V lead-acid extended battery cabinet purpose-built to expand runtime on Smart-UPS SRT 5KVA and 6KVA rack-mount systems. Occupying 3U of rack space, it delivers additional battery capacity in a black rack-mount chassis — the right choice when your standard UPS runtime falls short of what your critical load demands during extended outages.
At 200.6 lb (91 kg), the SRT192RMBPM is a substantial piece of infrastructure. Plan your rack rail support and floor loading before deployment — this is not a cabinet you add as an afterthought. Paired with a compatible Smart-UPS SRT RM unit, it extends the runtime window that separates a controlled shutdown from data loss or equipment damage.
Key Features
- 192V Lead-Acid Battery String: Matches the voltage architecture of the Smart-UPS SRT 5KVA and 6KVA RM platforms directly — no voltage conversion, no compatibility adapters required. The lead-acid chemistry is a proven, cost-effective choice for stationary UPS applications where weight is less of a constraint than total energy capacity.
- 3U Rack Form Factor: Three rack units keeps the footprint manageable relative to the runtime gain. In a standard 42U rack, you can add multiple battery cabinets without consuming the rack entirely, giving you a path to progressively longer runtime as your uptime requirements grow.
- 200.6 lb / 91 kg Installed Weight: The weight reflects a full battery string — this is what 192V of lead-acid capacity actually weighs. Verify your rack's static load rating before installing. Mid-mount or bottom-of-rack positioning is strongly recommended to keep the center of gravity low and avoid rail stress.
- Rack-Mounted Installation: Slides into a standard EIA 19-inch rack alongside the host UPS, keeping the battery extension co-located with the protected load. Cable management between the SRT192RMBPM and the UPS stays inside the rack rather than running across the floor.
- Black Chassis Finish: Matches the standard APC Smart-UPS SRT rack-mount color scheme — relevant if rack aesthetics matter in a customer-facing or co-location environment.
- Compatible with 5KVA and 6KVA SRT RM Models: Designed specifically for the Smart-UPS SRT family at these power tiers. Do not attempt to pair with lower-capacity SRT models or non-SRT APC lines — the 192V bus voltage is specific to this product tier.
Integration & Compatibility
The SRT192RMBPM is designed exclusively for the APC by Schneider Electric Smart-UPS SRT 5KVA and 6KVA rack-mount product family. It connects via the dedicated battery extension port on compatible SRT RM units — consult your UPS model's documentation to confirm the battery expansion connector and the maximum number of supported external battery cabinets before ordering multiples.
For data center and server room deployments, pair the SRT192RMBPM alongside a compatible rack-mount UPS to extend runtime for servers, storage arrays, and networking gear. If you are also evaluating power distribution or UPS accessories for the same rack, confirm total rack weight and PDU capacity at the planning stage — adding a 200.6 lb battery cabinet to an already-loaded rack is the kind of detail that surfaces problems during installation rather than during ordering.
For guidance on sizing extended runtime for your specific load, a UPS runtime and battery planning guide can help match battery cabinet count to your actual shutdown or hold-time requirement.
Frequently Asked Questions
Q: Which UPS models is the SRT192RMBPM compatible with?
A: The SRT192RMBPM is designed for use with APC Smart-UPS SRT 5KVA and 6KVA rack-mount (RM) models. The 192V battery bus voltage is specific to this product tier — do not pair with SRT models outside this power range without verifying compatibility in the UPS documentation.
Q: How much does the SRT192RMBPM weigh, and what are the rack installation requirements?
A: The installed weight is 200.6 lb (91 kg). Verify your rack's static load rating before installation. Bottom or mid-rack positioning is recommended to maintain a low center of gravity. The unit occupies 3U of standard EIA 19-inch rack space.
Q: What battery technology does the SRT192RMBPM use?
A: It uses a sealed lead-acid battery string at 192V. Lead-acid chemistry is standard for stationary UPS battery cabinets — well-suited to fixed rack installations where weight is acceptable and total energy capacity per dollar is a priority.
Q: Can I install multiple SRT192RMBPM cabinets on one UPS to extend runtime further?
A: APC Smart-UPS SRT models support a defined maximum number of external battery cabinets — consult your specific UPS model's documentation for that limit. Adding more than the supported number can exceed the UPS battery management circuit's capacity.
Q: What are the package dimensions for the SRT192RMBPM?
A: The packaged dimensions are 16.54 in H × 39.37 in W × 23.62 in D (42 cm × 100 cm × 60 cm). Plan receiving dock and aisle access accordingly — a fully packaged unit at 200+ lb requires appropriate material handling equipment.
The SRT192RMBPM is the one spec most integrators underestimate until they're standing in front of a loaded rack: 200.6 lb of lead-acid cells in a 3U chassis. Before this cabinet ships to site, I want to see a rack load calculation and a floor load confirmation — that weight is the whole story here, not the voltage or the form factor.
Technical Highlights:
- 192V Battery Bus: Directly matched to the SRT 5KVA/6KVA RM architecture — the UPS battery management circuitry is calibrated for this voltage string, which means charge balancing and runtime calculations work as designed without any field adjustment.
- 3U / 200.6 lb Density: You are fitting 91 kg of cells into 3 rack units. That ratio is why rack position matters — bottom-mounting this unit drops the rack center of gravity by several inches compared to mid-mounting, which matters if the rack is not bolted to the floor.
- Lead-Acid Chemistry: Reliable, field-replaceable, and widely stocked by APC service depots. In a fixed-rack infrastructure context (not mobile, not edge), lead-acid gives you the best capacity-per-dollar of any chemistry at this voltage level.
Deployment Considerations:
- Shipping carton dimensions run 39.37 in wide — confirm your equipment room door clearance and aisle width before scheduling delivery. A pallet jack or two-person lift is the minimum safe handling requirement at 200+ lb.
- The SRT192RMBPM has a defined maximum count per host UPS — exceeding it doesn't add more runtime, it risks overloading the battery management bus. Pull the UPS model's specification sheet and confirm the supported external cabinet count before quoting more than one cabinet per UPS.
This cabinet belongs in fixed data center rows, server closets, or colocation cages where the host SRT 5KVA or 6KVA RM unit is already installed and the runtime window needs to stretch from minutes to tens of minutes during utility events — not in edge deployments or mobile racks where weight is a constraint.
