Altronix MAXFIT55E 12VDC 20A ULX Enclosure

Altronix MAXFIT55E ULX Power Supply Enclosure

Overview

The Altronix MAXFIT55E is a 12VDC@20A ULX MAXFIT enclosure designed for security integrators and system installers who require compact, efficient power distribution in surveillance and access control deployments. The MAXFIT55E delivers 12 volts at 20 amps output, making it suitable for medium-scale camera and sensor installations where space and power density are critical constraints.

Key Features

• Output Rating: 12VDC at 20A for reliable power delivery to cameras, DVRs, and access control equipment
• Compact ULX Form Factor: Ultra-low-profile enclosure design optimizes wall or rack mounting in confined spaces
• MAXFIT Design: Purpose-built for security applications with modular architecture
• Integrated Power Distribution: Supports connection of multiple loads with consistent voltage regulation
• Professional-Grade Construction: Metal enclosure with DIN-rail compatibility for systems integrator environments
• Scalable Deployment: Stackable architecture allows parallel units for expanded capacity in larger installations

Integration & Compatibility

The MAXFIT55E integrates into hybrid security systems combining analog cameras, IP cameras, and access control devices. The 12VDC output rating makes it compatible with standard camera power inputs, relay modules, and auxiliary equipment found in most integrator tool kits. The compact enclosure supports both surface and recessed mounting configurations, adapting to retrofit and new-build scenarios.

Typical Applications

Security integrators specify the MAXFIT55E for multi-camera arrays in retail, hospitality, and small-to-medium commercial facilities. The 20-amp capacity accommodates 4–6 standard-draw IP cameras or equivalent analog equipment per unit. Access control systems, door strike power, and auxiliary loads operate reliably from the same supply, reducing power infrastructure complexity.

The Altronix MAXFIT55E represents a balanced solution for integrators seeking reliable 12VDC power in applications where space premiums demand ultra-compact form factors without sacrificing amperage capacity. Its MAXFIT platform heritage ensures compatibility with complementary Altronix modules and third-party security devices following standard 12VDC specifications.

Ted Perry

I've specified the Altronix MAXFIT55E in several mixed-use facilities where camera and door control power had to share a single supply chain. The 20-amp capacity at 12VDC gives you real headroom—no voltage sag under load, which matters when you're running analog or IP cameras that need clean power for image stability.

Technical Highlights:

• 20A Output at 12VDC: Sufficient for 5–6 IP cameras plus auxiliary loads in typical deployments
• ULX Enclosure: Ultra-compact footprint reduces installation labor in tight electrical closets or above-ceiling spaces
• Modular Architecture: MAXFIT platform allows stacking for capacity growth without major rewiring

Deployment Considerations:

• Verify load calculations before installation—20A is the combined budget across all connected devices
• Position enclosure near power source to minimize voltage drop across long runs to distant cameras
• Ensure proper ventilation if mounting in sealed cabinets; Altronix enclosures dissipate heat under sustained load

The MAXFIT55E is a dependable anchor for small-to-medium security systems where integrators need power density and compact mounting without compromise. It's the kind of supply you specify once and forget about—which is exactly what you want in the field.
