Din-Rail Battery Packs
RayTel RT-BPU-DR Industrial DC Battery Pack Units (BPU)

These compact, DIN-rail mounted 24VDC and 48VDC battery modules are designed to provide reliable, short-term power source for industrial networking and control equipment. When combined with RayTel Industrial Charge Control Units (CCU), It ensures continuous operation during power interruptions, safeguarding critical communications and automation systems.

• 24VDC or 48VDC - Supports both industrial automation and telecommunications power architectures with a common battery backup platform.
• Run Time Options - Multiple battery capacities including 1.2Ah or 4.5Ah capacity to match runtime requirements and load demands. Enables cost-effective right-sized deployments.
• Reliable Power Source - Delivers temporary backup power when primary power is lost. Maintains operation of critical equipment until power is restored or shutdown procedures are completed.
• DC UPS System Element - Integrates with compatible DC power and UPS charge controllers to create complete battery-backed power solutions. Keeps PLCs, HMIs, remote I/O, sensors, networking and edge devices online during power interruptions to preserve network connectivity and communications availability.
• DIN-Rail - Mounts directly to standard T35 DIN rail for quick integration into control cabinets and equipment enclosures.
• Maintenance-Free - AGM sealed lead-acid batteries eliminate routine maintenance requirements while delivering reliable standby performance. Spill-proof construction supports installation in industrial environments.
• Long Life - Up to 5 years of standby service life reduces replacement frequency and lowers operating costs.
• Serviceable - Depleted batteries can be replaced on-site without changing the entire assembly.
• Rugged Design - Powder-coated aluminum construction provides durability for control cabinet, telecom, and industrial use.
• Easy Installation - Removable screw terminals and externally accessible fuses simplify installation and maintenance. Reduces service time during battery replacement and system upgrades.

The RayTel RT-BPU-DR Industrial DC Battery Pack Units enable resilient networking and control infrastructure without the complexity of centralized UPS systems. By providing localized battery backup power source at the edge, they help maintain communications, preserve industrial processes, protect critical data, and improve overall system availability during unexpected power events.

The Battery Packs provide reliable standby power for critical 24VDC and 48VDC equipment operating in industrial, transportation, telecom, utility, and building automation environments.

Designed for integration with compatible DC power supplies and UPS charge controllers, these battery modules deliver uninterrupted operation during power outages, brownouts, and input power disturbances. Based on sealed AGM lead-acid battery technology, they offer maintenance-free operation, long standby life, and rapid deployment in DIN-rail control cabinets.

The battery pack is packaged in an Industrial-grade powder-coated metal enclosure with standard T35 DIN-rail compatibility.  Dual DIN-rail retention clips on select models for enhanced vibration resistance and mounting stability.  Removable terminal blocks and accessible fuse panel simplifies installation and maintenance.

Applications span Industrial Networking, Industrial Automation, Telecommunications, Building & Facility Management as well as Utilities & Transportation.
