Altronix AL1024ULXPD16CB 16-Output 24VDC Power Supply

Altronix AL1024ULXPD16CB 16-Output 24VDC Power Supply with Integrated Battery Charger

The AL1024ULXPD16CB is a 16-output 24VDC power supply purpose-built for distributed security and access control deployments where backup power and fault supervision are non-negotiable. Each of the 16 independent outputs delivers up to 10A at 24VDC — enough to power a multi-door access control system, a mixed array of locks and readers, or feed individual surveillance device circuits without daisy-chaining. The integrated battery charger eliminates the need for a separate charge controller, reducing wiring complexity and points of failure in UPS installations.

Key Features

• 16 independent 24VDC outputs at 10A per output maximum: Each channel can supply the full rated current independently. In practice, this means you can pull 10A on one output for a heavy-duty electric strike while other outputs handle lower-draw readers and sensors without interaction or voltage sag — a crucial advantage over single-output supplies that degrade under uneven load.
• Integrated battery charger: Supports automatic backup battery conditioning without requiring external charge modules. This streamlines system architecture, especially in retrofit installations where space or budget constraints limit equipment choices.
• AC fail supervision: Detects loss of input AC power and signals connected security controllers or alarm panels. Critical for triggering automated failover, lockdown sequences, or audit alerts during mains failure.
• Low battery supervision: Alerts the control system when backup battery voltage drops below usable threshold, preventing silent, catastrophic loss of power during extended outages. Works in tandem with battery presence detection to catch charger faults before they affect uptime.
• Battery presence detection: Confirms the charger is physically connected and functioning before relying on backup power. Prevents scenarios where a disconnected or failed battery module goes unnoticed until a real power loss occurs.
• UL listed for commercial security and industrial applications: Meets UL standards for fire alarm, access control, and surveillance power supply installations, simplifying code compliance review and insurance underwriting in regulated facilities.

Integration & Compatibility

The AL1024ULXPD16CB integrates into any 24VDC-based security infrastructure — multi-door controllers, card readers, electric locks, alarm panels, and low-voltage surveillance devices. Supervision relay outputs connect to industry-standard monitoring panels (FireLite, Honeywell, DSC, Napco, or equivalent) to log power state changes. No proprietary software or licensing required. The lifetime limited warranty covers defects in materials and workmanship, giving you long-term protection in facilities where power supply replacement is disruptive.

When to Choose a Different Model

If your deployment requires fewer than 5 outputs or needs only single-channel power conditioning, consider a lower-channel-count variant in the Altronix power supply family — it will be more economical and occupy less rack or wall space. If you need auxiliary functions such as siren drivers, relay outputs for remote signaling, or integrated UPS battery modules, evaluate Altronix modular power and battery systems, which stack to provide both power distribution and supplemental control logic. For small single-device backup scenarios, a standalone 24VDC UPS module may be sufficient.

Frequently Asked Questions

Q: Can I connect the AL1024ULXPD16CB to my existing 24VDC battery backup system?

A: Yes. The integrated charger is designed to manage and maintain 24VDC backup batteries. Connect the battery to the charger terminals, and the unit will automatically condition the battery and trigger supervision signals on AC loss or low voltage.

Q: What happens if I pull more than 10A from a single output?

A: Each output is current-limited and protected. Exceeding 10A will trigger thermal or electronic shutdown on that channel; other outputs remain unaffected. Verify your load current before deployment to avoid nuisance trips.

Q: Does the AL1024ULXPD16CB support daisy-chaining to multiple units?

A: No. Each unit is independent. For deployments exceeding 160A total 24VDC capacity, deploy multiple AL1024ULXPD16CB units on separate AC circuits with separate battery banks and supervision wiring.

Q: What battery types does the charger support?

A: The charger is compatible with standard sealed lead-acid (SLA) and gel-cell 24VDC batteries rated for security and UPS applications. Consult the datasheet for specific amp-hour and chemistry recommendations.

Q: How do I wire the supervision outputs to my alarm panel?

A: AC fail and low battery supervision outputs are relay contacts (normally open or closed, configurable) that wire directly to supervised input zones on any ONVIF-compatible or conventional alarm panel. No additional modules required.

Q: Is the AL1024ULXPD16CB NDAA or TAA compliant?

A: Compliance certifications are not listed in available technical data. Contact the manufacturer or your specialty distributor for current compliance documentation if required for federal or restricted procurement.

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

The AL1024ULXPD16CB solves a real problem in distributed access control: how to deliver independent 24VDC to 16 different circuits without voltage droop or cross-channel interference. The 10A per-output rating is the standout feature — it means you can feed a full-sized electric strike (8–10A draw) on one channel while readers, buttons, and sensor inputs sit comfortably on others without degradation. The integrated charger eliminates an entire bill-of-materials line item and a potential point of failure in UPS architectures.

Technical Highlights:

• 16 independent 10A outputs: Total available capacity of up to 160A (accounting for practical thermal limits). Uneven loading doesn't degrade performance on other channels — each output is internally isolated and regulated independently.
• AC fail and low battery supervision: Relay contacts alert your control system in real time to power events. Combined with battery presence detection, you eliminate the silent failure mode where a charger fault goes undetected until a mains outage occurs.
• Integrated battery charger: Removes the need for a separate charge controller or external UPS module, consolidating architecture and reducing cabinet clutter in retrofit installations where space and wiring runs are already constrained.

Deployment Considerations:

• Each output maxes at 10A; loads exceeding that threshold will trip the internal current limiter. Size your circuits carefully and test under worst-case simultaneous load before commissioning.
• Battery supervision is only as good as your alarm panel's response logic. Verify that your security controller is configured to log and act on AC fail and low battery events — dead battery alerts don't help if nobody checks the panel.

The AL1024ULXPD16CB is the right choice for multi-door access systems in commercial buildings, warehouse automation hubs, and security operations centers where reliable distributed 24VDC power and battery backup are baseline requirements. The independent per-output current rating and supervision features make it far more reliable than chaining generic multi-outlet supplies together.
