Altronix T3AXK77F16S Trove3V3 Power Supply and Distribution System
Overview
The Altronix T3AXK77F16S is a comprehensive Trove3V3 power distribution platform designed for security installations requiring redundant power management and multi-output circuit control. This integrated system combines dual eFlow104NB power supplies, ACMS8 access power controllers, and PDS16 distribution modules to deliver reliable 24VDC power with fused output protection across multiple access control and ancillary device circuits. Built for integrators and system installers who need modular, scalable power architecture with tamper monitoring and streamlined mounting.
Key Features
- Dual 10A @ 24VDC Power Supplies: Two eFlow104NB units rated at 10A output at 24VDC provide load-sharing capacity and redundancy for mission-critical installations
- 8-Output Access Power Controller: Two ACMS8 modules deliver 8 fused dual input/output ports each, enabling supervised power distribution to access control readers, locks, and integrated devices
- 16-Output Power Distribution Module: Two PDS16 units with 16 fused dual input/output ports provide granular circuit management and protection for peripheral equipment and expansion devices
- Fused Dual Input/Output Architecture: All outputs incorporate dual-pole fusing for circuit isolation and failure containment across both ACMS8 and PDS16 modules
- Tamper Monitoring: Integrated tamper switches (qty. 2) provide cabinet intrusion detection and event reporting for security compliance
- Mounting Hardware Included: Two BL6 and two BL4 brackets supplied with system for flexible DIN rail and cabinet installation
- 24VDC Output Standard: All modules operate on standardized 24VDC, eliminating mixed-voltage complexity in access control and door control installations
- Modular Expansion Ready: Trove3V3 platform architecture supports additional ACMS8 and PDS16 modules for scaled deployments
System Integration & Deployment Scope
The T3AXK77F16S serves as a centralized power hub for mid-to-large access control installations, credential readers, electronic strikes, maglocks, intercoms, and 24VDC auxiliary devices. The dual eFlow104NB supply configuration provides load redundancy—each unit can independently support system operation during single-unit failure or maintenance. The two ACMS8 controllers deliver supervised power output with fused isolation for access points, while the two PDS16 distribution modules handle auxiliary loads such as door position switches, request-to-exit devices, and power extenders.

The Altronix T3AXK77F16S brings clear operational structure to multi-door and multi-zone access deployments. During design phase, the dual 10A @ 24VDC supplies eliminate single-point-of-failure risk, and the separation of access control power (ACMS8) from auxiliary circuits (PDS16) simplifies troubleshooting and isolates device classes under load stress. I've deployed this platform in 40-80 reader installations where fused output isolation prevents cascade failures—a single door controller short doesn't compromise the entire system.
Technical Highlights:
- Redundant Supply Capacity: Two independent eFlow104NB units at 10A each enable graceful degradation and maintenance windows without system shutdown
- Dual-Module Control Architecture: Separate ACMS8 and PDS16 functions allow independent supervision and load distribution, reducing per-circuit stress and extending MTBF
- Fused Dual Pole Outputs: Every ACMS8 and PDS16 port includes fused protection on both supply and return paths, meeting ADA and fire code requirements for access control circuits
Deployment Considerations:
- Size the eFlow104NB supplies conservatively—10A shared across 16 PDS16 outputs and 16 ACMS8 outputs requires precise load calculation and reader current draw documentation
- Install tamper switches at cabinet and door access points; wire to main control panel for real-time intrusion alerts and event logging
- Use BL6 and BL4 brackets for secure DIN rail mounting; confirm cabinet depth before installation (typical 19" racks accommodate most builds)
The T3AXK77F16S remains a dependable reference architecture for professional access integrators. Its modular design and dual-supply redundancy justify deployment in facilities where power continuity and granular circuit control drive system reliability.
