Altronix MAXFIT7524AS 12/24VDC 20A 12-Output Fused Power Distribution Module
Overview
The Altronix MAXFIT7524AS is a compact, fuse-protected power distribution module designed for multi-device surveillance and access control installations where clean, individually protected power feeds matter. Rated for 12/24VDC at 20A total output and accepting input from 5 to 24 VDC, the MAXFIT7524AS integrates into distributed camera runs, door controller arrays, and mixed-device panels without requiring a dedicated power supply enclosure for each run. At 7.30 × 4.10 × 1.25 inches and under 1 lb, it mounts cleanly inside most standard enclosures — leaving room for the rest of your hardware.
Key Features
- 12 Individually Fuse-Protected Outputs: Each output carries its own fuse, so a shorted camera or reader drops only that circuit — not your entire camera run. On a 12-camera installation, this is the difference between one blind spot and a complete outage during a fault condition.
- 12/24VDC Dual-Voltage Operation at 20A: The 20A aggregate rating supports dense device arrays — roughly 16 standard IP cameras drawing 1.2A each at 12VDC, or a mix of cameras and card readers at 24VDC. Confirm your aggregate draw before specifying.
- Wide Input Range (5–24 VDC): Accepts input from 5 to 24 VDC, making the MAXFIT7524AS compatible with a broad range of upstream power supplies without a voltage converter in the chain. Useful when integrating into existing enclosures with varied supply voltages.
- Compact Form Factor (7.30 × 4.10 × 1.25 in): The slim 1.25-inch depth allows flush installation inside standard Altronix enclosures and most third-party metal cabinets without consuming vertical real estate needed for transformers or batteries.
- Includes 2 × ACMS12 Modules: Ships with two ACMS12 fuse management modules — the hardware you need to provision and monitor individual output circuits is in the box, not an add-on line item.
- Lightweight at 0.95 lbs: Ceiling or wall enclosure installations don't require supplemental support — the module's own weight won't stress a standard enclosure mounting rail or backplane.
Integration & Compatibility
The MAXFIT7524AS is built for the Altronix power distribution lineup and slots into the broader security power supply ecosystem used in commercial surveillance and access control. Its wide input voltage range makes it a practical fit across mixed-brand enclosure builds. Integrators deploying IP cameras or multi-door access control panels on a shared power infrastructure should verify per-output current requirements against the 20A aggregate budget — the fuse protection ensures individual fault isolation, but total draw management remains a design responsibility. For planning multi-camera power runs, the PoE and power planning guide covers load budgeting fundamentals that apply equally to centralized low-voltage DC distributions like this one. Pair with compatible access control hardware for a fully fused, distributed 12/24VDC backbone.
Frequently Asked Questions
Q: What is the input voltage range for the MAXFIT7524AS?
A: The MAXFIT7524AS accepts input from 5 to 24 VDC, supporting integration with a wide range of upstream power supplies without additional voltage conversion.
Q: How many outputs does the MAXFIT7524AS provide, and are they individually protected?
A: The module provides 12 outputs, each individually fuse-protected. A fault on one output circuit will not affect the remaining 11, which is critical for multi-camera and multi-reader installations.
Q: What is the total output capacity of the MAXFIT7524AS?
A: The MAXFIT7524AS is rated for 20A total output at 12 or 24 VDC. Integrators should budget aggregate device draw against this ceiling before finalizing device counts per module.
Q: Does the MAXFIT7524AS ship with fuse modules included?
A: Yes — the MAXFIT7524AS includes 2 × ACMS12 fuse management modules. No separate accessory purchase is required to provision output circuits out of the box.
Q: What are the physical dimensions of the MAXFIT7524AS?
A: The module measures 7.30 × 4.10 × 1.25 inches and weighs 0.95 lbs, sized for installation inside standard security enclosures without consuming significant cabinet space.
The MAXFIT7524AS is the module I reach for when a project calls for a dense, fused DC distribution backbone inside a single enclosure — specifically because its 5–24 VDC input range means I'm not locked to a single upstream supply spec. On a recent 10-camera retail job, it let us drop one MAXFIT7524AS per IDF closet and feed the whole camera run from a single 24VDC supply, with every camera circuit independently fused.
Technical Highlights:
- 12 Fuse-Protected Outputs: Individual fusing per output means a shorted camera or reader takes down only that circuit. On a 12-device run, fault isolation is the difference between one camera offline and an entire wing dark.
- 20A Aggregate at 12/24VDC: At 12VDC and 1.2A per camera, the 20A budget covers up to 16 standard IP cameras per module — a realistic ceiling for a single IDF cabinet run.
- 5–24 VDC Input Range: Broad input compatibility eliminates the need for voltage-matching converters when integrating into enclosures with mixed or non-standard supply voltages — a common situation on retrofit projects.
Deployment Considerations:
- Always calculate your aggregate device draw before committing to a device count per module — the 20A ceiling is shared across all 12 outputs, and heavier PTZ or multi-sensor cameras can quickly compress that budget.
- The 1.25-inch depth is slim but verify your target enclosure's internal clearance before ordering, particularly on older cabinets with shallow backplanes or front-mounted terminal blocks.
The MAXFIT7524AS is best suited for commercial retrofit and new-build projects where per-circuit fault isolation and enclosure-space efficiency are both design constraints — warehouse camera deployments and multi-reader access control panels being the most common fit.
