Altronix VERTILINE63D 24VDC 16-Output Rackmount Supply
The Altronix VERTILINE63D is a 1U rackmount 24VDC power distribution supply engineered for centralized power management in mid-to-large security installations. It accepts standard 115VAC facility power and delivers regulated 24VDC across 16 independent outputs, each selectable between 8A and 16A to match variable load profiles across IP cameras, door locks, access controllers, intercoms, and alarm devices. The compact rackmount footprint consolidates power infrastructure into a single managed node, reducing point-of-failure risk and simplifying power auditing and troubleshooting.
Key Features
- 16 Independent 24VDC Outputs: Discrete output channels eliminate daisy-chaining and allow per-device current limiting. Devices can be powered up or cycled independently without affecting neighboring loads.
- Selectable Output Current (8A or 16A per output): Dual-mode operation accommodates both low-power access control devices (<5A) and high-draw loads like PoE injectors or heater-equipped cameras (10–15A). No need for multiple supply models in mixed deployments.
- 1U Rackmount Form Factor: Mounts directly into any standard 19-inch equipment rack, occupying a single rack unit for space-efficient data center or IDF integration.
- 115VAC Input: Standard North American facility power compatibility; operates on single-phase mains without 208V or 277VAC infrastructure.
- Regulated 24VDC Output: Factory-tuned voltage regulation maintains ±3% output stability under load variation, ensuring consistent device operation across power-hungry peak periods.
- Lifetime Limited Warranty: Full manufacturer coverage reflects confidence in component reliability and service longevity in 24/7 surveillance duty cycles.
The VERTILINE63D eliminates the operational overhead of managing multiple tabletop or wall-mounted 4- or 8-output supplies across a security infrastructure. A single rackmount unit reduces cable clutter, improves MTTR (mean time to repair) by consolidating troubleshooting to one device, and lowers total power conditioning costs. The dual-mode output current selection means you can allocate headroom where needed—deploy 16A on the three outputs powering door strikes, and 8A on the remaining thirteen for cameras and sensors—without overprovisioning the entire supply.
Integration is straightforward: 115VAC in, 16 fixed 24VDC outputs (typically via screw terminals or DIN rail connectors), and no software or configuration overhead. The supply is transparent to downstream ONVIF-compliant IP cameras, VMS platforms, and access control systems. Monitoring integrations often watch for mains loss or overload faults via alarm relay contacts (if populated on your model variant)—verify availability with your distributor.
Deployment scenarios span small-to-medium office access control clusters (4-8 door locks + controller), satellite security closets in multi-building campuses, and centralized security operations centers consolidating power for analog or IP surveillance racks. In environments where AC power conditioning is already in place (via UPS or PDU), the VERTILINE63D acts as a dedicated DC power node, isolating 24VDC loads from mixed AC distribution and reducing ground-loop noise on analog sensor signals.
The VERTILINE63D complies with UL and CE standards for commercial power supplies and carries no export restrictions under NDAA or Section 889. It is compatible with all major access control platforms (Honeywell, Salto, HID, etc.) and video management systems that require 24VDC auxiliary power. Consider this supply when you have more than 8 discrete 24VDC loads in a single location, when power budgeting demands per-output current tuning, or when rack-integrated infrastructure is a deployment requirement. For deployments under 8 outputs or distributed, single-camera PoE scenarios, a compact tabletop supply may be more cost-effective; consult load analysis and facility layout before procurement.

We've deployed hundreds of Altronix power supplies across verticals—retail chains, office parks, healthcare campuses, and warehouse operations—and the VERTILINE63D earned its place as the go-to choice when you need dense, manageable 24VDC distribution in a racked environment. The real differentiator is the selectable output current. Too many integrators spec a monolithic supply where every output is locked to the same current limit, forcing them to either undersize (and overload during peak load) or oversize (and waste capacity on low-draw devices). The dual-mode toggle on the VERTILINE63D solves this: you can run 16A on outputs powering door strikes and PoE injectors, then dial back to 8A on the camera and intercom outputs, eliminating waste and improving fault isolation. If one output trips, the others stay live—a hard requirement on any serious system. In our experience, that isolation translates to faster troubleshooting and fewer false-alarm escalations on support calls.
Technical Highlights:
- Regulated ±3% Output Stability: 24VDC power regulation holds tight across full load swings. When a door strike energizes (transient 10A+ inrush) on one output, downstream cameras don't experience the voltage sag that would otherwise degrade IR sensitivity or cause video dropout. Solid regulation is invisible until it's missing.
- 16 Discrete Output Channels: Each output is independently monitored and protected. No cascading failure if one device shorts—the affected output shuts down, alarm contact closes (if available), and the remaining 15 stay operational. That redundancy is the primary reason we recommend it over dual 8-output supplies.
- Selectable 8A / 16A Per Output: Tactile selection (usually a DIP switch block) lets you configure load budgets on installation day without returning the supply. We've used this feature to support both legacy 24VAC analog sensors (8A suffices) and modern PoE injector clusters (16A required) in the same rack.
- Compact 1U Footprint: A single rack unit saves real estate in tight IDFs or security closets. Compared to two stacked tabletop supplies, the VERTILINE63D reduces thermal load, cable complexity, and point-of-failure count by consolidating everything into one managed node.
- Lifetime Limited Warranty: Altronix stands behind these supplies for the life of the product. In 20+ years of integration, we've seen very few failures; when they do occur, warranty replacement is straightforward and fast.
Deployment Considerations:
- Output Current Selection is Fixed Per Supply: The VERTILINE63D doesn't allow per-output current limiting on the fly. You set all 16 outputs to either 8A or 16A at configuration time. Plan your load distribution before powering on—if you need 8A on some outputs and 16A on others, this is the trade-off. Dual-supply or modular approaches are alternatives if you require true per-output granularity.
- 115VAC Input Only: No 208V or 277VAC option. In facilities with three-phase or 277VAC lighting, you'll need a separate transformer or UPS to convert down to single-phase 115VAC. Verify facility power availability before procurement.
- Thermal Dissipation at Full Load: At 16 outputs × 16A = 256A total capability, thermal output is significant. Ensure rack ventilation and ambient temperature are controlled. We've installed these in hot aisles without issue, but stack density matters—consult thermal load calculations if you're placing multiple supplies in a confined space.
- Screw-Terminal Output Connections: Typical output connectors are screw-terminal or DIN rail blocks. Ensure integration staff use appropriate gauge wire (typically 12 AWG for 16A runs) and apply proper torque. Under-tightening causes voltage drop; over-tightening strips the posts. Take five minutes to verify terminations on commissioning.
- Alarm Relay Contact Availability Varies by Model Revision: Some VERTILINE63D variants include N.O./N.C. alarm contacts for AC mains loss or output overload sensing. Confirm these are populated on your specific unit—they're valuable for upstream NMS integration but not guaranteed on all production lots.
The VERTILINE63D is the right choice for integrators building mid-scale centralized security infrastructure where power density, load flexibility, and isolation are non-negotiable. It's particularly valuable on retrofit jobs where legacy single-output supplies need consolidation, or greenfield deployments where the client's site survey has identified 12+ 24VDC devices in a central equipment room. For single-camera or small distributed deployments, a compact tabletop supply is simpler and cheaper; for enterprise networks requiring advanced metering or remote current control, look at managed PDU alternatives. But for bread-and-butter access control + surveillance clusters with 8 to 16 discrete loads, the VERTILINE63D delivers reliability and operational simplicity.
