Altronix BC750 2-Power Supply & 2-Sub-Assembly Enclosure

The Altronix BC750 is a dual power supply and dual sub-assembly enclosure designed for modular security system architecture. This configuration supports distributed power management and component consolidation in mid-scale installations where multiple power sources and auxiliary assemblies require organized, protected housing within a single unit.

Overview

The BC750 enclosure accommodates two independent power supply modules and two sub-assembly boards, enabling flexible system topologies across access control, video surveillance, and integrated security networks. This modular approach reduces installation footprint while maintaining electrical isolation and thermal management across separate power domains. Integrators benefit from the ability to standardize on a single enclosure form factor across diverse project types, simplifying procurement, inventory, and field deployment workflows.

Key Features

• Dual Power Supply Bays: Houses two independent power supply modules, enabling redundancy or separate circuit feeds for isolated subsystems
• Dual Sub-Assembly Slots: Accommodates two auxiliary circuit boards for distribution, relay control, battery backup management, or signal conditioning functions
• Modular Architecture: Component slots designed for standard Altronix power supply and sub-assembly form factors, ensuring compatibility across product generations
• Compact Footprint: Consolidates multiple functional modules into a single wall-mount or DIN-rail-compatible enclosure, reducing panel real estate and cable routing complexity
• Thermal Management: Internal layout optimized for airflow around power supplies and active components, supporting continuous operation in ambient temperatures typical of equipment rooms and outdoor cabinets
• Electrical Isolation: Separate internal busing and terminal blocks for each power supply enable independent load distribution and fault isolation without cross-circuit current bleed

Integration & Compatibility

The BC750 integrates with the full Altronix modular power and control ecosystem. Power supplies rated for 12 VDC or 24 VDC operation slot directly into dedicated bays; sub-assembly options include battery backup modules, relay packs, surge suppression cards, and signal distribution boards. Security integrators can mix and match sub-assemblies based on project requirements without redesigning enclosure infrastructure. The BC750 is frequently deployed in access control hubs, video head-end rooms, and distributed network nodes where centralized power and control consolidation reduces field wiring labor and improves system serviceability.

This enclosure design supports both hardwired and networked security architectures. When paired with Altronix PoE power supplies and network interface sub-assemblies, the BC750 becomes a compact edge power distribution point for IP camera arrays, wireless bridge nodes, or multi-building security networks.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've specified the BC750 in several mid-scale distributed security deployments where equipment consolidation was critical to reducing site complexity. The dual power supply and dual sub-assembly architecture is particularly useful when you need isolated power feeds for separate circuits—access control on one supply, video distribution on another—without running multiple cable tray assemblies. The BC750 handles that elegantly.

Technical Highlights:

• Modular Power Configuration: Two independent power bays allow you to stage redundant supplies (same-model pairs) or mixed-voltage supplies (12 VDC + 24 VDC) depending on downstream load requirements
• Sub-Assembly Flexibility: The two sub-assembly slots accept Altronix battery backup boards, relay controls, or surge suppressors without enclosure redesign or additional wiring harnesses

Deployment Considerations:

• Size the power supplies independently; do not assume both bays must be identical—your load analysis may call for different current ratings in each slot
• Plan sub-assembly allocation early in design phase; verify terminal block pitch and wire gauge compatibility with your control wiring standards
• Position the BC750 in climate-controlled equipment rooms when possible; if outdoor mounting is necessary, pair with a weatherproof outer cabinet and verify thermal load under peak summer ambient conditions

The BC750 is a solid, no-frills consolidation enclosure that scales from small multi-building campuses to medium-sized enterprise security deployments. It won't do any one thing spectacularly, but it does multiple things—power distribution, sub-assembly hosting, component isolation—reliably and predictably. Recommended for integrators who value standardization and field serviceability over novelty.
