APC by Schneider Electric SRT192RMBP 192VDC 3U Rack External Battery Pack
Overview
The APC by Schneider Electric SRT192RMBP is a 192VDC external battery pack designed to extend the runtime of compatible Smart-UPS SRT online double-conversion systems. Occupying 3U of rack space, it connects directly to the UPS to add battery capacity without changing your power infrastructure — no additional power conditioning, no new UPS investment. If your runtime requirements outgrow what the internal batteries can deliver, the SRT192RMBP is the purpose-built extension for the SRT line.
This is a rack-mount unit: 432 mm wide (standard 19-inch rack), 130 mm tall (3U), and 682 mm deep. Plan your rack depth accordingly — at 682 mm, it requires a full-depth or near-full-depth enclosure. The unit ships ready to install and is RoHS-compliant, which matters for deployments in environments with strict materials regulations or sustainability requirements.
Key Features
- 192VDC Battery Voltage: Matched to the Smart-UPS SRT high-voltage architecture. This voltage tier is what enables the SRT series to achieve the efficiency and runtime characteristics it's known for — swapping in a mismatched voltage pack would void compatibility entirely. Always verify your UPS model accepts a 192V external pack before ordering.
- 3U Rack Form Factor (432 × 130 × 682 mm): Fits standard 19-inch rack enclosures. At 3U, you're trading rack real estate for extended runtime. Depth at 682 mm is the critical measurement — measure your cabinet interior depth, not just the mounting rail span, before specifying this unit.
- Operating Temperature Range 0–40°C: Suitable for conditioned server rooms and typical data center environments. Not rated for uncontrolled ambient spaces or outdoor enclosures — if your UPS is in a telecom hut or industrial environment that runs hot, verify the thermal ceiling holds before deploying.
- Storage Temperature Range -15–45°C: Provides a reasonable buffer for short-term storage or transit in cold climates. Batteries degrade faster at temperature extremes, so staging in a controlled environment before installation is the right practice.
- Operating Humidity 0–95% (non-condensing): Covers the humidity range found in most commercial and enterprise facilities. The non-condensing qualification is standard — avoid deploying in spaces with active condensation risk.
- Operating Altitude up to 3,000 m (9,843 ft): Covers virtually all terrestrial data center and commercial deployments. Non-operating altitude ceiling of 15,000 m means air freight is not a concern for logistics.
- RoHS Compliance: Meets European Union Restriction of Hazardous Substances requirements. Relevant for organizations with environmental procurement policies or international deployments where RoHS certification is a contract requirement.
Integration & Compatibility
The SRT192RMBP is engineered for the Smart-UPS SRT product family — specifically the models that operate on a 192VDC external battery bus. Not all SRT models share the same voltage architecture: the SRT line spans 48V, 96V, and 192V configurations depending on UPS capacity. Confirm your UPS model's external battery voltage before specifying the SRT192RMBP. Pairing a 192V pack with a 96V-bus UPS is not supported and will prevent proper recognition. Review your UPS documentation or the APC by Schneider Electric product line to cross-reference compatible UPS models.
Installation is straightforward for anyone familiar with rack UPS systems: the battery pack connects via the external battery connector on the rear of the compatible UPS. No additional controller or interface module is typically required. Consult your UPS installation guide for the specific cable and connection procedure — cable is not always included with the battery pack, so verify power accessories needed before deployment.
For large installations running multiple network switches, servers, or IP security infrastructure on protected circuits, the SRT192RMBP provides the incremental runtime that keeps systems online through extended outages — particularly relevant for surveillance and access control systems where loss of power means loss of coverage.
Frequently Asked Questions
Q: Which APC Smart-UPS SRT models are compatible with the SRT192RMBP?
A: The SRT192RMBP is designed for Smart-UPS SRT models that use a 192VDC external battery bus. Not all SRT models share this voltage — verify your UPS model's external battery voltage in its specification sheet before ordering. APC's compatibility documentation for your specific UPS model is the authoritative reference.
Q: How much rack space does the SRT192RMBP require?
A: The SRT192RMBP occupies 3U of rack space and measures 432 mm wide × 130 mm tall × 682 mm deep. Ensure your rack enclosure has at least 682 mm of usable interior depth to accommodate the unit fully.
Q: Is the SRT192RMBP compatible with standard 19-inch racks?
A: Yes. At 432 mm wide, the SRT192RMBP is designed for standard 19-inch rack mounting. Confirm your rack's rail-to-rail depth accommodates the 682 mm depth of the unit.
Q: What is the operating temperature range for the SRT192RMBP?
A: The SRT192RMBP operates between 0°C and 40°C. It is intended for climate-controlled environments such as server rooms and data centers — not for uncontrolled ambient or outdoor deployments.
Q: Is the SRT192RMBP RoHS compliant?
A: Yes. The SRT192RMBP carries RoHS compliance certification, meeting the EU Restriction of Hazardous Substances directive.
Q: Does the SRT192RMBP include the connection cable to the UPS?
A: Package contents should be verified at time of purchase. Connection cable inclusion varies by configuration — confirm what is included before finalizing your order to avoid installation delays.
The SRT192RMBP is purpose-built for one job: adding battery capacity to the Smart-UPS SRT high-voltage platform. The 192VDC architecture is the key detail here — this is not a universal battery pack, and that specificity is intentional. The SRT line's double-conversion topology runs most efficiently at this voltage tier, so APC engineered the external packs to match exactly. If you are specifying extended runtime for a high-capacity SRT system, the SRT192RMBP is the correct path.
Technical Highlights:
- 192VDC Nominal Voltage: Matched to the SRT high-voltage bus — critical for proper UPS recognition and runtime calculation. A voltage mismatch will cause the UPS to reject or fail to recognize the pack entirely.
- 3U / 682 mm Deep Rack Profile: The 682 mm depth is the dimension most likely to create installation problems. Many two-post and shallow four-post racks top out at 600–650 mm of usable depth — measure before you order.
- 0–40°C Operating Range: Standard for sealed VRLA chemistry. Running the pack above 40°C accelerates battery degradation and shortens service life — keep ambient temperature in check if this is going into a high-density rack row.
Deployment Considerations:
- Confirm the exact SRT UPS model number accepts a 192V external pack — the SRT line spans multiple voltage configurations and a 96V-bus SRT will not work with this unit.
- At a package weight of 105.5 kg, two-person installation is not optional — plan lift assistance or a mechanical aid for rack integration, especially in elevated mounting positions.
Best fit: enterprise data centers or large commercial facilities running high-capacity Smart-UPS SRT systems where the internal battery runtime is insufficient for the required hold-time during extended utility outages or generator transfer delays.
