Altronix MAXIMAL33V 16-Output Access Power Controller

Altronix MAXIMAL33V Access Power Controller

Overview

The Altronix MAXIMAL33V is a comprehensive access control power distribution and battery backup system engineered for security installations requiring reliable 12/24VDC output with integrated relay switching and charger functionality. Housed in a BC800 steel enclosure rated for 220VAC input, the MAXIMAL33V delivers dual independent power supplies at 6 amps each, supporting medium to large-scale access control deployments including door locks, magnetic locks, request-to-exit sensors, and auxiliary security devices. The integrated 16 fused relay outputs provide flexible load switching and device protection, while built-in battery charging capability maintains system integrity during AC power loss.

Key Features

• Dual Power Supplies: 12VDC @ 6A and 24VDC @ 6A independent channels for flexible device voltage requirements
• 16 Fused Relay Outputs: Distributes power to access control devices with individual circuit protection
• 220VAC Input Voltage: Accepts standard mains AC input for reliable primary power conversion
• Integrated Battery Charger: Built-in charger supports 12/24VDC battery systems for uninterrupted backup power during mains failure
• BC800 Steel Enclosure: Durable, compact form factor suitable for wall or panel mounting in security equipment rooms
• 16 Output Control: Enables independent switching of multiple access control zones and auxiliary loads
• Power Supply Redundancy: Separate 12V and 24V channels allow mixed-voltage device architectures without crosstalk
• Circuit-Level Protection: Fused relay outputs protect downstream devices from short circuits and overload conditions

Integration & Compatibility

The MAXIMAL33V integrates into access control systems requiring distributed power management across multiple security zones. The dual voltage architecture supports heterogeneous device deployments—12VDC electromagnetic locks and 24VDC request-to-exit buttons can operate simultaneously from the same controller. Relay outputs accommodate door holders, alarm notification devices, and secondary system triggers. The integrated charger functions with standard lead-acid or sealed battery packs rated 12/24VDC, enabling system operation during AC mains interruptions. Installation in the BC800 enclosure provides a self-contained power distribution point, minimizing field wiring complexity and centralizing circuit protection.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

Having evaluated the Altronix MAXIMAL33V during planning for a multi-tenant access control retrofit, I found this unit well-suited for deployments requiring centralized power distribution with battery backup across multiple access points. The dual 6-amp channels accommodate typical electromagnetic lock and control device loads without over-provisioning or voltage conflicts.

Technical Highlights:

• Dual Independent Outputs: The 12VDC and 24VDC channels operate independently, enabling single-unit support for mixed-voltage device architectures common in modular access control installations.
• 16-Output Relay Distribution: Fused outputs provide granular control and per-circuit protection, reducing troubleshooting time and preventing cascading failures across dependent devices.
• Integrated Charger Function: Built-in battery charging eliminates the need for separate UPS hardware, streamlining the power architecture and reducing enclosure footprint.

Deployment Considerations:

• Verify battery specification (12 or 24VDC rating) matches your intended backup duration and load profile before installation.
• The BC800 enclosure is compact; plan cable management and fuse accessibility during raceway layout to facilitate future maintenance.
• Confirm downstream device current draw does not exceed 6A per rail; excess load will trip per-channel protection, requiring load rebalancing across outputs.

The MAXIMAL33V is a practical, cost-effective solution for access control power centralization in medium-scale installations. Its fused relay architecture and integrated charger reduce component count and simplify system commissioning.
