Altronix MAXIMAL3DV 220VAC 16-Output PTC Power Supply with Battery Backup
Overview
The Altronix MAXIMAL3DV is a centralized surveillance power supply built for international 220VAC deployments that need supervised, individually protected outputs for cameras, access control readers, or alarm devices. Sixteen PTC-resettable outputs — selectable between 12VDC and 24VDC — combined with AC fail, battery fail, and battery presence supervision make it a practical hub for mid-to-large installations where individual circuit protection and system status monitoring are non-negotiable. If you are specifying Altronix power distribution for a multi-camera or multi-reader deployment running on 220VAC mains, this unit is engineered for that scope.
Key Features
- 220VAC Input (198–256VAC, 50/60Hz): Accepts the full international mains range, so it installs without a transformer or voltage converter in 220VAC facilities — hospitals, manufacturing plants, and government sites outside North America can drop this directly onto local power.
- 16 PTC-Protected Outputs at 2.5A Each: Each output is independently protected by a self-resetting PTC fuse. A shorted camera or reader clears itself without requiring a technician to swap a fuse — the affected circuit recovers once the fault is removed, keeping the rest of the distribution unaffected.
- Selectable 12VDC or 24VDC Output: Configure the output voltage for your device mix. Run 12VDC for standard IP cameras or 24VDC for long-run access control wiring where voltage drop is a concern — no separate supply needed for mixed-voltage sites.
- 5.4A Maximum Output / 3.5A Auxiliary Output: The 5.4A aggregate ceiling per output group keeps you honest on load planning, while the 3.5A auxiliary output feeds panel boards or secondary distribution without straining the main outputs.
- Battery Backup — 12AH / 12VDC: Supports a 12AH battery for ride-through during outages. For camera systems with local recording, this is the difference between a gap in the timeline and continuous coverage when mains power drops.
- Selectable Fire Alarm Disconnect: Lets you wire the supply into a fire alarm panel so cameras or access control devices de-energize on alarm — required in many AHJ-governed installations without adding external relays.
- Three-Status Supervision (AC Fail, Battery Fail, Battery Presence): Each condition is individually supervised and reportable to a panel or monitoring system. You know immediately whether the unit lost mains, the battery has degraded, or the battery has been removed — not just that something is wrong.
- Operating Range 0°C to 49°C: Rated for mechanical rooms, closets, and indoor riser locations that see heat buildup. Storage is rated to 70°C for hot-climate warehousing before installation.
- 1.5A Input Current, 5A/250V Input Fuse: Modest draw on the 220VAC circuit — a single 15A breaker feeds multiple units if load sharing is needed. The input fuse provides upstream protection without requiring a dedicated breaker per unit.
Integration and Compatibility
The MAXIMAL3DV integrates into installations using access control systems or multi-camera surveillance infrastructure where centralized power distribution with circuit-level supervision is required. The selectable fire alarm disconnect output is designed to interface directly with addressable or conventional fire alarm panels, simplifying AHJ compliance on combined security and life-safety projects. At 26" x 19" x 6.25" and 42.3 lbs, plan for a dedicated wall-mount or rack shelf — this is not a compact unit.
Frequently Asked Questions
Q: What input voltage does the MAXIMAL3DV require?
A: The MAXIMAL3DV is designed for 220VAC input with an operating range of 198VAC to 256VAC at 50/60Hz. It is not a dual-voltage unit and is not intended for 120VAC North American mains without a step-up transformer.
Q: Can I mix 12VDC and 24VDC devices on the same unit?
A: The output voltage on the MAXIMAL3DV is selectable — either 12VDC or 24VDC — but it is a single selection for the unit, not configurable per output channel. If your installation requires both voltages simultaneously, you would need separate supplies for each voltage level.
Q: What happens when one output shorts out?
A: Each of the 16 outputs is individually protected by a self-resetting PTC fuse rated at 2.5A. When a fault clears, the affected output resets automatically — no fuse replacement required, and the remaining 15 outputs continue operating normally.
Q: Does the MAXIMAL3DV support battery backup, and what battery size is compatible?
A: Yes. The MAXIMAL3DV supports a 12AH / 12VDC backup battery. Battery presence, battery fail, and AC fail are all individually supervised and reportable to a connected panel or monitoring system.
Q: Is the fire alarm disconnect feature always active?
A: No — the fire alarm disconnect is selectable. You can configure it to de-energize outputs on a fire alarm signal when your installation requires it, or leave it inactive if not applicable to your site.
The MAXIMAL3DV is the unit I reach for on 220VAC international projects where the integrator needs sixteen individually supervised outputs, a battery-backed ride-through, and fire alarm integration — all in a single enclosure. The selectable fire alarm disconnect alone eliminates a relay module on compliant AHJ sites, and the three-status supervision (AC fail, battery fail, battery presence) means your monitoring panel sees exactly which condition triggered, not just a generic fault.
Technical Highlights:
- PTC Self-Resetting Protection: 2.5A PTC per output means a camera short auto-clears after the fault is removed — no truck roll to swap a fuse on a 16-camera distribution point.
- 220VAC Input Range: 198–256VAC tolerance at 50/60Hz covers international mains variance without additional conditioning hardware — straightforward on European, Middle Eastern, and APAC sites.
- Battery Supervision Trio: Discrete AC fail, battery fail, and battery presence outputs give integrators the signal granularity panel manufacturers expect; you're not inferring battery state from a single fault output.
Deployment Considerations:
- At 42.3 lbs and 26" x 19" x 6.25", this unit needs a rated wall anchor or a full shelf in a 24" deep rack — do not underestimate the physical plant requirement before specifying.
- Output voltage is a unit-wide selection (12VDC or 24VDC), not per-channel — if your device mix requires both voltages at the same distribution point, plan a second supply rather than trying to split this one.
The MAXIMAL3DV is the right call for international 220VAC facilities — manufacturing plants, government buildings, or hospital campuses — where a single supervised power distribution point needs to serve 12–16 cameras or access control readers with fire alarm coordination built in.
