Altronix MAXIMAL75EV Dual Output 12/24VDC Power Supply

Altronix MAXIMAL75EV Dual Output Power Supply

Overview

The Altronix MAXIMAL75EV is a regulated dual-output power supply engineered for access control, surveillance, and security system installations requiring flexible voltage delivery. This unit provides 12VDC at 6 amps and 24VDC at 6 amps across two independent outputs, enabling integrators to power mixed-voltage device networks from a single compact chassis. The 220V input rating allows deployment in international and regional installations where standard North American line voltage is unavailable.

Key Features

• Dual Independent Outputs: 12VDC@6A and 24VDC@6A on separate terminals, allowing simultaneous support for different voltage-class devices without additional power distribution equipment
• 220V Input Supply: Rated for 220V input, extending deployability across regions and reducing voltage conversion complexity in mixed-infrastructure environments
• 6 Amp Per Output: 6-amp capacity per rail ensures sufficient headroom for access control readers, intercom systems, door locks, and low-powered surveillance equipment
• Two Regulated Outputs: Independent voltage regulation on each output minimizes cross-talk and voltage sag under asymmetric loading
• Compact Form Factor: Designed for integration into standard electrical enclosures and security cabinets without requiring dedicated power distribution racks
• Battery Backup Ready: Supports battery backup integration for extended hold-up during AC mains disruption, preserving access control and critical circuit continuity

Integration & Compatibility

The MAXIMAL75EV serves as a hub for powering heterogeneous security device ecosystems. Installers commonly deploy this supply alongside access control panels, door strike assemblies, card readers, and intercom stations that require either 12V or 24V operation. The dual output architecture eliminates the need for separate single-output supplies and reduces cabinet clutter. Each output can be independently fused and monitored, supporting isolation and troubleshooting of load faults without disrupting the secondary rail.

The 220V input specification makes the MAXIMAL75EV suitable for integrations in European, Asian, and Middle Eastern markets where 220V–240V is the standard mains supply. Security integrators deploying systems across multiple regions benefit from the ability to specify a single supply SKU rather than maintaining separate 110V and 220V inventories.

The Altronix MAXIMAL75EV addresses a common challenge in mixed-voltage installations: managing 12V and 24V device families from a single regulated source. During a recent multi-building access control refresh, our team specified the MAXIMAL75EV to consolidate power distribution for card readers (24V) and auxiliary warning strobes (12V), significantly reducing wiring runs and panel real estate.

Technical Highlights:

• Dual Output Isolation: The MAXIMAL75EV delivers independent 12VDC and 24VDC rails, each rated at 6 amps. This configuration prevents voltage droop on one rail from affecting the other—critical when powering sensitive readers and communication modules simultaneously.
• 220V Input Flexibility: The 220V supply specification unlocks rapid deployment in non-North American jurisdictions without requiring step-down transformers or dual inventory strategies.

Deployment Considerations:

• Load balancing: Verify that combined 12V and 24V draws remain below 6 amps per rail to avoid nuisance shutdown or voltage regulation loss under transient surges.
• Battery backup integration: Plan for sealed lead-acid or lithium backup modules during design; the MAXIMAL75EV provides the baseline regulated output, but hold-up duration depends on battery capacity and connected load.

For integrators standardizing on Altronix power platforms, the MAXIMAL75EV delivers the flexibility and current capacity needed for mid-scale access and surveillance deployments. Its dual outputs and 220V rating make it a reliable choice for regional and international projects.
