Altronix AL1024ULXPD8CB 8-Output 24VDC Power Supply/Charger
The Altronix AL1024ULXPD8CB is a UL Listed, eight-output 24VDC regulated power supply engineered to support distributed security infrastructure where power continuity and circuit independence matter. Each output delivers 10A at 24VDC, yielding 80A total capacity across eight independent, protected circuits — enough to power dozens of access readers, door strikes, mag locks, IP cameras, and encoders from a single chassis. Built-in battery management and automatic charging eliminate the need for external chargers, and three supervision functions (AC Fail, Low Battery, Battery Presence) provide system-level visibility into power integrity without external monitoring hardware.
Key Features
- Eight Independent 24VDC Outputs at 10A Each: Capacity to handle multiple readers, locks, or camera encoder feeds simultaneously. Independent outputs mean a fault or short on one circuit will not cascade to others — critical for mission-critical access or camera installations where a single failure cannot take down the entire feed.
- Integrated Battery Charging and Backup Management: No separate battery charger required. The AL1024ULXPD8CB manages charge cycles and monitors battery health automatically, reducing BOM complexity and installation footprint in cabinet-constrained environments.
- AC Fail Supervision: Notifies the system control panel or monitoring device the instant mains power is lost, allowing graceful failover to battery-backed circuits or triggering emergency lockdown procedures before reserve capacity is exhausted.
- Low Battery Supervision: Monitors backup reserve status continuously. Alerts operators before battery depletion occurs, preventing unexpected dropouts during extended power loss scenarios.
- Battery Presence Supervision: Detects missing, disconnected, or failed batteries before an actual outage. Early warning of charger/backup degradation lets you schedule replacement during maintenance windows, not emergency callouts.
- UL Listed Construction: Meets electrical safety codes for most commercial and institutional security installations, simplifying code compliance documentation and insurer review.
- Lifetime Limited Warranty: Covers manufacturing defects across the operational life of the unit, reducing risk of unexpected replacement costs.
Integration & Compatibility
The AL1024ULXPD8CB integrates into any 24VDC security ecosystem — access control panels, door controllers, IP camera encoders, intercom systems, and gate operators all consume standard 24VDC. Supervision outputs (AC Fail, Low Battery, Battery Presence) connect to a control panel input or dedicated monitoring relay, enabling automated alerting and logging within a networked video recorder or access control management platform.
Typical deployments include multi-reader access control clusters (each reader on its own supervised output), distributed camera-and-codec installations across separate facility zones, and gate/door automation systems where loss of power to any single circuit must not affect others. The 10A-per-output specification is important: it constrains load-per-circuit but ensures no single faulty device can collapse system power distribution.
When to Choose a Different Model
If your installation requires fewer than eight outputs, consider a lower-channel variant in the Altronix power supply family. If you need higher per-output current (e.g. 20A or greater per circuit), evaluate higher-capacity models. If battery backup is not required, non-charger regulated supplies will be more cost-effective.
Frequently Asked Questions
Q: What battery should I use with the AL1024ULXPD8CB?
A: The unit is designed for sealed lead-acid (SLA) backup batteries. Consult the product datasheet or contact the manufacturer for compatible battery model numbers and AH ratings. Battery selection depends on desired runtime — larger AH capacity extends backup duration.
Q: Can I mix outputs — use some at 10A and others at lower current on the same unit?
A: Yes. Each output is independently protected and regulated. You may load outputs asymmetrically — some at 10A, others at 2A or 5A — as long as no individual output exceeds its 10A rating and total load stays within the unit's AC input capacity.
Q: How do I wire the supervision outputs to my control panel?
A: Supervision outputs are dry relay contacts (normally open/closed state). Connect them to corresponding input terminals on your access control or video management panel. Logic (normally open or closed) is user-configurable at the panel level.
Q: Is the AL1024ULXPD8CB suitable for outdoor or wet environments?
A: The unit is designed for indoor cabinet or wall-mounted installation. For outdoor or wet environments, house the AL1024ULXPD8CB in a protective enclosure or NEMA-rated cabinet to prevent corrosion and water ingress.
Q: What happens if mains power fails before the battery is fully charged?
A: The unit will immediately switch to battery power and deliver 24VDC to supervised circuits. Charge status is reported via Low Battery and Battery Presence supervision — the system can log this event and notify operators of the reduced reserve.

The AL1024ULXPD8CB is a workhorse for distributed 24VDC security infrastructure — specifically where you need eight independent, supervised power rails without splitters or daisy-chaining. The 10A-per-output spec is the key constraint to understand: it's conservative by design, which means no single faulty reader, lock, or encoder can drag down power to other circuits. That matters more than raw megawattage when you're integrating access control, video, and intercom across a mid-to-large facility.
Technical Highlights:
- 10A per output at 24VDC (80A total capacity): Enough for 2–3 mag locks, 4–6 card readers, or 8–10 IP camera encoders per output, depending on draw. The independence prevents cascade failures — a shorted lock doesn't take down cameras on another circuit.
- Integrated battery management with three supervision modes: AC Fail, Low Battery, and Battery Presence eliminate the need for a separate charger and external monitoring relay in most integrations. You get three contact closures to your control panel; the panel handles alerting and logging.
- UL Listed construction: Simplifies code sign-off in commercial installations and reduces insurer objections to unvetted power distribution hardware.
Deployment Considerations:
- The 10A limit per output is real — sum your reader, lock, and codec draws carefully. If you have a 7A mag lock, you've got 3A headroom on that output; pair it with a 2A reader and you're at capacity.
- Battery runtime is entirely dependent on battery AH selection and total load on backup circuits. A 7AH SLA will hold a 5A load for ~1.4 hours; size accordingly for your facility's expected outage duration.
- Install the unit in a climate-controlled cabinet or wall-mounted enclosure. The charger and battery management circuits generate modest heat; outdoor or uncontrolled-temperature installations shorten battery life.
Deploy the AL1024ULXPD8CB in access control clusters (multi-reader sites, turnstiles, badge readers across a floor), distributed video-and-encoder camera nodes (each zone on its own circuit), or mixed-device security networks (readers + door strikes + IP cameras) where redundancy and supervision-level visibility are required. Avoid it if you need single outputs rated above 10A or fewer than four separate circuits — those need different SKUs.
