Altronix MAXFIT13E Dual-Output Expandable Power Supply Enclosure

Overview

The Altronix MAXFIT13E is a wall-mount expandable power system built for commercial and enterprise security installations that need simultaneous 12VDC and 24VDC power distribution with full battery backup — all inside a single, code-compliant BC750 enclosure. Drawing 115VAC at 7A and delivering Class 2-rated outputs, the MAXFIT13E pairs two single-output power supply/chargers in one enclosure, giving integrators the flexibility to run mixed-voltage device loads without a second cabinet. It's a practical choice for mid-size access control, intrusion, or video installations where the electrical room is already tight and conduit runs are fixed.

If you're specifying power distribution across a range of security power supplies, the MAXFIT13E belongs in the conversation any time dual-voltage output and local battery backup are both requirements. For a broader look at the Altronix power and access control line, including single-output and multi-output variants, the full catalog covers nearly every installation footprint.

Key Features

• Dual Configurable Output — Up to 10A Combined: Option A delivers 12VDC or 24VDC at 6A per supply; Option B delivers 12VDC at 4A or 24VDC at 3A. Running both simultaneously means you can power 24VDC door controllers on one rail and 12VDC cameras or locks on the other — no separate enclosure, no added conduit run.
• Class 2 Rated Power-Limited Outputs: Class 2 compliance means these outputs meet NEC low-voltage wiring requirements out of the box. For integrators pulling permits on commercial jobs, this eliminates the inspection headaches that come with non-listed power sources.
• Instantaneous Failover on AC Loss: The moment 115VAC drops, the system transfers to battery with no detectable gap. For access control panels or alarm communicators that can't tolerate even a brief power interruption, instantaneous failover is non-negotiable — and this unit delivers it.
• Up to 4 × 12VDC/12AH Battery Capacity: The BC750 enclosure accommodates four 12AH sealed lead-acid or gel batteries internally. That's 48AH of local reserve — enough to sustain a typical multi-reader access panel through an extended outage without an external battery cabinet. Batteries are sold separately; plan that into your BOM.
