APC SRT48RMBP APC Smart-UPS SRT 48V 1kVA 1.5kVA RM Battery Pack SRT48RMBP

Data Sheet: APC Smart-UPS SRT 48V 1kVA/1.5kVA Rackmount Extended Runtime Battery Pack (SRT48RMBP)

The APC SRT48RMBP is a high-density, rack-optimized external battery pack (XLBP) designed to deliver scalable runtime extension for mission-critical APC Smart-UPS On-Line infrastructure. Built natively in a 2U horizontal configuration, this module integrates seamlessly into 19-inch IT cabinets protecting edge computing nodes, standard networking stacks, and data center clusters. Operating on a stable 48V DC bus, the unit provides smart cell-level monitoring and a reliable hot-swappable topology to maintain continuous operational uptime throughout extended power grid dropouts.

Core Technical Specifications

• System DC Voltage: 48 V DC

• Battery Configuration Type: Maintenance-free, leak-proof, sealed Valve Regulated Lead-Acid (VRLA) with suspended electrolyte

• Internal Battery Cartridge Core: Contains two (2) hot-swappable, factory-matched internal replacement cartridges (APCRBC155)

• Scalable Bus Matrix: Supports parallel daisy-chaining of up to 10 external battery packs to a single host UPS for massive backup capacity scaling

• Form Factor Profile: 2U Rack-Mounted out-of-the-box (Includes heavy-duty 19-inch rack mounting brackets; convertible to standalone tower configurations using optional stabilization feet accessories)

• Chassis Dimensions ($H \times W \times D$): 85 mm $\times$ 432 mm $\times$ 536 mm (3.35″ $\times$ 17.01″ $\times$ 21.10″)

• Net System Weight: 29.90 kg (65.92 lbs)

• Environmental Range: 0°C to 40°C operating temperature; 0–95% non-condensing relative humidity

• Sustainability & Compliance: Green Premium certified, REACh chemical tracking compliant, EU RoHS compliant, and California Proposition 65 tracked

Equipment Variants for SKYRS Pakistan

SKYRS supervises international hardware supply links, certified cell string-matching, and custom data center staging across Pakistan for all operational variations within this 48V platform:

• SRT48RMBP: The premier rackmount configuration detailed here, shipping factory-equipped with 19-inch mounting brackets for structural alignment inside standardized network enclosures.

• SRT48BP: The standalone vertical floor-tower counterpart, arriving pre-bundled with vertical support stabilizing brackets for spaces lacking dedicated server cabinets.

• SRT48RMBP-US: The specialized TAA-compliant equivalent variation sharing identical electrical parameters but conforming to strict United States Trade Agreements Act manufacturing trace regulations, sourced by SKYRS predominantly for diplomatic installations, defense cells, and compliance-mandated multinational datacenters inside Pakistan.

Deployment, Installation, and Configuration

Structural Loading and Thermal Planning

• Rack Equilibrium Placement: Because each 2U module introduces a dense 29.90 kg load, complex multi-pack string deployments add extensive structural stress to an equipment rack. SKYRS site engineers position these external battery modules at the lowest available slots within the server enclosure to safeguard structural integrity and maintain a low center of gravity.

• Ambient Thermal Controls: VRLA battery capacity retention and total operational life drop drastically when exposed to elevated temperatures. SKYRS deployment environments mandate a climate-controlled cooling envelope targeting a continuous ambient temperature between 20°C and 25°C.

• Exhaust Ventilation Boundaries: Provide a minimum of 100 mm of open spatial clearance directly behind the rear chassis loop to prevent heat traps and encourage continuous airflow.

Physical Installation Sequence

1. Cabinet Integration: Mount the heavy-duty 4-post adjustable telescoping rail kits (such as SRTRK4) into the designated 2U slot of the 19-inch server rack. Carefully slide the 29.90 kg SRT48RMBP chassis onto the rail channels and secure the structural front rack ears to the vertical posts using standard M6 cage nuts.

2. DC Power Bus Linkage: Access the polarized, high-current DC connector port located at the rear of the host online UPS. Firmly plug the integrated color-coded DC power cable from the SRT48RMBP into the host terminal until the locking tabs snap firmly into place.

3. Multi-Pack String Expansion: To configure highly scalable backup arrays, plug successive battery modules in series by linking the input cable of the next unit directly into the available output battery terminal of the preceding module.

Software Configuration and Host Validation Protocol

1. Intelligent Firmware Synchronization: Modern APC Smart-UPS On-Line engines feature built-in backplane logic that automatically senses the attachment of external battery packs via the DC bus connection.

2. Local LCD Verification: Navigate to the “Configuration” menu on the host UPS front multi-color backlit graphical LCD panel. Access the “Battery” tracking tab and confirm that the total number of connected external units recognized by the core system reflects the physical quantity deployed.

3. Management Card Parameter Mapping: Log into the secure web interface of your pre-installed or upgraded APC Network Management Card (NMC3). Verify that the system’s runtime forecasting has successfully updated across the expanded 48V DC parallel matrix. Within your PowerChute Network Shutdown console, re-calibrate customized load-shedding configurations and low-battery shutdown intervals to maximize infrastructure resilience during prolonged utility grid blackouts.
