Altronix POE240 56VDC 240W Power Supply Board

Altronix POE240 56VDC Power Supply/Charger Board

Overview

The Altronix POE240 is a 56VDC, 240-watt power supply and charger board designed for professional security integration, access control, and networked device deployment. This board-level power solution delivers regulated output suitable for systems requiring sustained high-current 56VDC distribution with integrated battery backup charging capability. Built for integrators and system designers who need reliable, compact power architecture without sacrificing capacity or control flexibility.

Key Features

• 56VDC Output Voltage: Optimized for modern PoE and access control infrastructure requiring elevated DC voltage distribution
• 240W Power Capacity: Sufficient output to support multiple powered devices or high-draw subsystems from a single board-level source
• Integrated Battery Charger: Built-in charging circuit enables seamless backup battery integration for uninterrupted operation during mains failure
• Board-Level Form Factor: Compact design allows flexible mounting in cabinets, control panels, or custom enclosures for OEM and integrator applications
• Power Supply and Charger Combined: Single-unit solution eliminates the need for separate charging infrastructure, reducing complexity and footprint
• Professional-Grade Architecture: Engineered for 24/7 continuous operation in security, access control, and networked systems

Integration and Compatibility

The POE240 integrates naturally into Altronix control ecosystems and third-party systems requiring regulated 56VDC rails. The board format supports direct cabinet integration, DIN-rail auxiliary mounting, or custom panel integration. System designers can leverage the integrated battery charger to maintain uptime across backup battery banks without external charging modules. The 240-watt capacity accommodates mid-to-large scale PoE distribution, multi-door access control, and networked camera power delivery when paired with appropriate infrastructure planning.

Integrators should verify input voltage availability and battery backup requirements at the design stage. The POE240 is suitable for primary and secondary power distribution in larger control rooms, distributed cabinet networks, and dedicated security appliance cabinets where board-level power efficiency and space constraints favor compact solutions over modular external supplies.

Typical Applications

• Access control system primary or secondary power distribution
• PoE infrastructure power supply for networked security devices
• Backup power charging in cabinet-mounted security systems
• Multi-device power consolidation in control room environments
• OEM integration where compact board-level power is required

Karl Wilson

The Altronix POE240 addresses a specific but common integrator challenge: consolidating power supply and battery charging into a single board-level component. In cabinet-constrained deployments where external power supplies and separate chargers compete for DIN rail or shelf space, the POE240 eliminates that friction. I've evaluated this board during the planning phase of mid-scale access control rollouts, and the 56VDC/240W rating sits in a practical middle ground—substantial enough for multi-reader or multi-camera subsystems, but not so large that thermal or spatial management becomes problematic.

Technical Highlights:

• Integrated Architecture: Combined power supply and charger eliminates the need for external charging modules, simplifying BOM and reducing panel real estate
• 56VDC Output Rail: Optimized voltage level for modern PoE infrastructure and access control equipment, balancing efficiency and compatibility with standard regulatory frameworks
• 240W Capacity: Sufficient headroom for typical multi-device deployments without requiring cascaded supplies or complex load balancing

Deployment Considerations:

• Confirm input voltage source and redundancy topology before cabinet design; the POE240 assumes stable mains or UPS input
• Size backup battery bank relative to the integrated charger capacity and expected hold-up time; oversized batteries may require extended charge cycles
• Verify thermal environment in the target cabinet to ensure cooling adequacy during sustained high-draw periods
• Plan for monitoring and supervision connectivity if remote power status feedback is required in your control system

The POE240 is a straightforward, well-scoped solution for integrators building cabinet-based access control or PoE distribution. It performs exactly what it's specified to do—deliver regulated 56VDC and charge backup batteries—without unnecessary complexity. Recommended for systems where board-level power footprint and integrated charging are valued trade-offs.
