Altronix MAXFIT7712APS 24VDC 20A Power Distribution Module
Overview
The Altronix MAXFIT7712APS is a compact 24VDC power module rated at 20A, designed for direct integration with Altronix ACMS12 access control management systems and PDS16 power distribution solutions. At just 1.45 lbs and measuring 5.375 x 1.00 x 4.25 inches, this module is built to slot into structured security power supply enclosures without consuming excess rack or cabinet real estate — a practical consideration when you are fitting multiple power zones into a single enclosure. For integrators deploying Altronix power and access control infrastructure, the MAXFIT7712APS is a purpose-built fit within the MAXFIT product family.
Key Features
- 24VDC Output Voltage: Delivers a regulated 24VDC output — the standard rail for most commercial access control hardware, locking hardware, and peripheral devices. Running a single voltage across your installation simplifies wiring, reduces component count, and eliminates the need for additional step-down converters at the device level.
- 20A Output Current: A 20-amp current capacity provides enough headroom to drive multiple locks, readers, and auxiliary devices simultaneously without hitting thermal limits. This is the spec to validate when calculating aggregate load across your locking schedule — 20A at 24VDC gives you 480W of usable output before you need to consider a second module or a larger supply.
- ACMS12 Compatibility: Direct compatibility with the Altronix ACMS12 means the MAXFIT7712APS integrates into Altronix's access control management chassis without adapters or custom wiring harnesses. If your project already specifies the ACMS12, this module drops in as an expected component rather than a workaround.
- PDS16 Compatibility: Pairing with the PDS16 power distribution board enables structured, fused output distribution across up to 16 individually protected circuits. That matters on multi-door installations where a single shorted lock should not pull down power to an entire wing — per-circuit protection isolates faults.
- Compact MAXFIT Form Factor: At 5.375 x 1.00 x 4.25 inches, this module is engineered for density. In enclosures where space is already allocated and fixed, a module that fits the MAXFIT chassis without mechanical modification saves installation time and avoids the cost of a larger enclosure.
- Low Profile Weight: Weighing 1.45 lbs, the MAXFIT7712APS adds minimal mechanical load to wall-mounted or rack-mounted enclosures, which is relevant when calculating total enclosure weight on drywall or lightweight panel installations where anchor ratings matter.
Integration and Compatibility
The MAXFIT7712APS is specifically matched to the Altronix ACMS12 access control management system and the PDS16 power distribution board. Integrators building out access control power supplies on the Altronix MAXFIT platform should verify their enclosure model supports this module's 5.375 x 1.00 x 4.25 inch footprint before ordering. The 24VDC / 20A output profile aligns with standard commercial locking hardware voltage requirements, but always sum your worst-case simultaneous load across all connected devices — door strikes, magnetic locks, readers, and REX devices — against the 20A ceiling before commissioning. For multi-module deployments on a shared PoE or power distribution backbone, confirm upstream supply capacity can support the aggregate draw of all installed MAXFIT modules in the enclosure.
Frequently Asked Questions
Q: What output voltage and current does the MAXFIT7712APS provide?
A: The MAXFIT7712APS outputs 24VDC at up to 20A, providing 480W of capacity for connected access control and security devices.
Q: Which Altronix systems is the MAXFIT7712APS designed to integrate with?
A: This module is purpose-built for use with the Altronix ACMS12 access control management system and the PDS16 power distribution board within the MAXFIT enclosure family.
Q: What are the physical dimensions of the MAXFIT7712APS?
A: The module measures 5.375 inches wide, 1.00 inch tall, and 4.25 inches deep, and weighs 1.45 lbs — designed for compact integration within MAXFIT enclosures.
Q: Can the MAXFIT7712APS support multiple locking devices simultaneously?
A: Yes. The 20A output rating provides enough capacity to drive multiple locks, readers, and auxiliary devices concurrently, provided total simultaneous load stays within the 20A ceiling. Always calculate worst-case aggregate draw before commissioning.
Q: Is the MAXFIT7712APS compatible with standard commercial access control voltage requirements?
A: Yes. Its 24VDC output aligns with the standard voltage used by the majority of commercial door controllers, magnetic locks, electric strikes, and card readers.
The MAXFIT7712APS is the module I specify when a project is already committed to the Altronix MAXFIT platform and needs a dedicated 24VDC / 20A supply rail that drops directly into the ACMS12 chassis without mechanical compromise. At 5.375 x 1.00 x 4.25 inches, it is built for density — you are not trading enclosure space or adding standoffs to make it fit.
Technical Highlights:
- 20A at 24VDC: That is 480W of usable output — enough to drive a dense multi-door wing with magnetic locks, readers, and REX devices on a single module before you need to parallelize or add a second supply rail.
- ACMS12 direct integration: No adapter brackets, no custom harness. The module is matched to the ACMS12 chassis, which cuts installation time on projects where the access control platform is already specified.
- PDS16 pairing: Combined with the PDS16 distribution board, each of the 16 output circuits gets individual overcurrent protection — a fault on one door does not take down adjacent zones, which is the behavior you need on healthcare or data center door schedules where uptime per zone is load-bearing.
Deployment Considerations:
- Before installing, sum worst-case simultaneous load across every device on the module — strikes, maglocks, readers, REX — against the 20A ceiling. A multi-door wing with high-hold-force maglocks can approach that limit faster than the door count alone suggests.
- At 1.45 lbs the module is light, but validate the total enclosure weight (module plus other installed MAXFIT hardware) against your wall anchor rating if the enclosure is surface-mounted on drywall or lightweight panel — cumulative weight adds up across fully populated enclosures.
The MAXFIT7712APS earns its place on commercial multi-door access control projects — particularly healthcare corridors, education campuses, or corporate facilities — where the Altronix MAXFIT ecosystem is the specified platform and per-circuit fault isolation via the PDS16 is a system requirement, not a nice-to-have.
