Altronix MAXIMAL11DV 16-Output Access Control & Surveillance Power Supply

Overview

The Altronix MAXIMAL11DV is a multi-output power distribution unit built for international access control and surveillance deployments running on 220VAC mains. Configurable for either 12VDC at 8A or 24VDC at 6A across 16 individually protected outputs, it gives integrators the flexibility to match load requirements on a per-device basis without adding a secondary supply or external distribution block. If you're commissioning a multi-door access control system, a medium-density IP camera installation, or a hybrid panel room in a 220VAC market, the MAXIMAL11DV is engineered to handle that distribution load in a single rackmountable enclosure.

The unit accepts input across a wide range — 198VAC to 256VAC at 50/60Hz — which means it holds regulation even on noisy or brownout-prone commercial utility feeds common in international deployments. CE certification confirms it has cleared European electromagnetic and safety compliance requirements, a baseline requirement for most EU and Middle Eastern system integrations.

Key Features

• Dual-voltage output flexibility (12VDC or 24VDC): Running at 12VDC yields 8A total capacity across the 16 outputs; switch to 24VDC and you get 6A. That distinction matters when you're mixing low-voltage cameras (typically 12VDC) with access control hardware (often 24VDC) — configure to match the dominant load or install separate units per voltage rail rather than mixing voltages on one bus.
• 16 individually protected outputs at 2.5A each: Each output is rated for 2.5A, so a fault or short on one circuit — a wiring error during install, a failed lock sounder, a damaged door controller — doesn't take down adjacent devices. In a 16-door or 16-camera deployment, that isolation is the difference between a one-device service call and a system-wide outage.
• Wide input voltage window (198VAC to 256VAC): A ±13% tolerance on the nominal 220VAC input handles real-world utility variation. Sites with undersized transformers, long feeder runs, or peak-load voltage sag don't need a separate line conditioner ahead of this unit.
• 50/60Hz dual-frequency input: Usable on any international grid without jumper changes or model variants — relevant when the same BOM is being used across multiple countries or when a regional distributor stocks a single SKU for multiple markets.
• CE certification: Required for legal sale and installation in European Economic Area countries and increasingly referenced as a minimum bar in Middle Eastern and Asian government procurement. Avoids re-testing or supplemental compliance work at commissioning.
• Large-format enclosure (6.25 × 19.00 × 26.00 in, 40 lbs): The physical footprint is sized for a standard 19-inch equipment rack. At 40 lbs the unit needs proper rack rail support — plan for at least 2U vented shelf or four-post rack mounting rather than a two-post relay rack without support rails. Cabinet depth clearance of 26 inches is required; verify your rack cabinet's usable depth before ordering.

Integration & Compatibility

The MAXIMAL11DV fits into any deployment where the field devices — magnetic locks, electric strikes, door controllers, analog or IP cameras — accept 12VDC or 24VDC input and draw no more than 2.5A per output. It is not a PoE supply; IP cameras on this unit require a separate PoE injector or switch. Pair it with a compatible access control panel ecosystem when distributing power to door hardware across a multi-entry facility. For sites running Altronix's broader Altronix power and access control line, this unit integrates cleanly alongside their access control power systems. When sizing, account for inrush current on lock or strike loads — sustained 2.5A per output, but electromechanical lock inrush can momentarily exceed nameplate draw on energize. Review your power supply selection guide for load calculation methodology before finalizing the design. If your deployment is a US 120VAC installation, a different Altronix variant in the MAXIMAL family is the correct unit — the MAXIMAL11DV is explicitly rated for 220VAC input only.

Frequently Asked Questions

Q: What is the total output current capacity of the MAXIMAL11DV at 12VDC versus 24VDC?

A: At 12VDC, the MAXIMAL11DV delivers a total of 8A across all 16 outputs. At 24VDC, total output capacity is 6A. Each individual output is rated at 2.5A regardless of the selected voltage.

Q: Is the MAXIMAL11DV suitable for 120VAC installations in North America?

A: No. The MAXIMAL11DV is designed for 220VAC input (198VAC to 256VAC range). North American 120VAC sites require a different Altronix model. Using this unit on a 120VAC feed is outside its rated operating parameters.

Q: Does the MAXIMAL11DV support PoE output for IP cameras?

A: No. The MAXIMAL11DV provides 12VDC or 24VDC low-voltage DC output only. It does not deliver Power over Ethernet. IP cameras requiring PoE need a separate PoE switch or injector; this unit can power analog cameras, access control hardware, and other DC-powered field devices.

Q: What certifications does the MAXIMAL11DV carry?

A: The MAXIMAL11DV carries CE certification, confirming it meets European electromagnetic compatibility and safety directives. This is the verified certification from source evidence. Verify any additional regional certifications directly with Altronix for your specific jurisdiction.

Q: How many rack units does the MAXIMAL11DV occupy, and what are the depth requirements?

A: The enclosure measures 6.25 × 19.00 × 26.00 inches. The 19-inch width is standard rack width. Cabinet depth clearance of at least 26 inches is required. Plan for a supported rack shelf or four-post mounting given the 40 lb installed weight.

Q: Can both 12VDC and 24VDC outputs be used simultaneously on the same MAXIMAL11DV unit?

A: The MAXIMAL11DV is configured for one output voltage at a time — either 12VDC at 8A total or 24VDC at 6A total across all 16 outputs. It is not a dual-bus unit that provides both voltages simultaneously. Mixed-voltage deployments require separate units per voltage rail.

Karl Wilson

The MAXIMAL11DV is the unit I reach for on international projects where the panel room is running 220VAC and you need 16 independently protected DC outputs without bolting on a secondary distribution board. The 198–256VAC input window is the detail that actually earns its keep — on sites with long transformer secondary runs or marginal utility quality, that tolerance absorbs what would otherwise be a regulation problem for tighter supplies.

Technical Highlights:

• 16 outputs at 2.5A each: Per-output overcurrent protection means a wiring fault on door 7 doesn't cascade to doors 1–6 and 8–16. On a multi-door deployment, that isolation is the spec that prevents a single install error from becoming a building-wide lockout.
• 12VDC @ 8A / 24VDC @ 6A switchable: The voltage selection determines total available current — 8A at 12V, 6A at 24V. At 2.5A per output you won't load all 16 outputs to maximum simultaneously on either rail; plan your load budget per output and verify the aggregate doesn't exceed the bus total before finalizing the design.
• CE certification on a 220VAC platform: For EU and Middle Eastern government or commercial projects, CE is a procurement checkbox. Having it native to the unit eliminates a compliance conversation at commissioning that would otherwise add days to a project close-out.

Deployment Considerations:

• The enclosure is 26 inches deep and weighs 40 lbs — confirm your rack cabinet's usable interior depth and rail load rating before specifying. A standard 24-inch-depth two-post rack won't fit this unit; four-post or vented shelf mounting in a deep cabinet is the right approach.
• This is strictly a DC distribution supply — it has no PoE output, no battery backup circuit, and no built-in monitoring. If your access control design requires supervised power or battery standby, you'll need to add those elements separately upstream or alongside this unit.

The MAXIMAL11DV is the right fit for a 220VAC panel room supporting a 16-door or 16-camera installation — specifically in international markets where CE compliance is required and per-circuit fault isolation is a design requirement rather than a nice-to-have.
