Altronix AL1024ULXR 24VDC 10A Power Supply Charger
The Altronix AL1024ULXR is a 24VDC regulated power supply and charger designed to deliver continuous, monitored power to security and access control installations that demand uninterrupted operation. This unit combines primary 24VDC power distribution with integrated battery charging and AC/battery status monitoring, eliminating the need for separate charger and supply components in access control, surveillance, alarm, and gate control deployments.
Key Features
- 24VDC 10A regulated output: Delivers 240W of power capacity — enough to support multiple door locks, card readers, and control modules simultaneously without voltage sag. The regulated output ensures stable operation across mixed loads.
- Integrated battery charging: Built-in charger eliminates the need for a separate charging supply. During normal AC operation, the unit maintains a connected backup battery at full charge, ready for seamless failover if AC is lost.
- AC input monitoring: Continuously tracks incoming AC power. The moment AC fails, the unit switches to battery without interrupting downstream devices — critical for access control and alarm systems where momentary gaps cause lockouts or missed events.
- Battery status monitoring: Provides real-time visibility into backup battery condition. Integrators can detect a failing or discharged battery before an outage occurs, avoiding surprise failures in the field.
- Continuous duty rated: Designed and tested for 24/7 operation in climate-controlled equipment rooms, utility closets, and control enclosures. No warm-up cycle or thermal throttling under normal loads.
- Lifetime Limited Warranty: Altronix backs the unit with a lifetime limited warranty, transferable to end users. Parts and labor coverage reduces the total cost of ownership over a multi-year deployment.
Typical Deployment Scenarios
The AL1024ULXR excels in access control system backup configurations, where loss of power to door locks, card readers, or electronic strike plates can result in either a security breach or a lockout. In surveillance applications, this unit powers edge-based alarm or door-sensor modules that feed into the main NVR or management system. Gate and perimeter door control systems benefit from the battery-backed 24VDC rail, ensuring gate operators and control logic remain powered during power events. Alarm system control panels requiring 24VDC often integrate this supply for both primary operation and battery charger functionality.
Integration & Compatibility
The AL1024ULXR outputs standard regulated 24VDC, compatible with virtually all 24VDC security and control equipment. The unit does not impose vendor lock-in and works alongside third-party batteries, door locks, readers, and control logic. AC input operates on standard 110–240V power, requiring only a standard wall outlet or distribution circuit. For large installations requiring multiple power rails or higher capacity, multiple AL1024ULXR units can be deployed in parallel or in separate zones of the building, each backing a logical subset of devices. Consult the detailed datasheet for wiring schematics and battery sizing guidance specific to your load profile and desired runtime.
Frequently Asked Questions
Q: What battery types does the AL1024ULXR support?
A: The unit charges standard lead-acid and sealed lead-acid (SLA) batteries commonly used in security backup systems. Refer to the product datasheet for recommended capacity ranges and charging parameters for your specific deployment.
Q: Can the AL1024ULXR power multiple door locks and card readers at the same time?
A: Yes. The 10A capacity (240W at 24VDC) supports multiple simultaneous loads. Standard electronic strikes draw 500–800mA each, and card readers typically draw 100–300mA. Calculate your peak concurrent load to confirm headroom.
Q: What happens if AC power fails while the battery is also discharged?
A: Output voltage drops as the battery depletes. Most access control logic will continue operating at reduced battery voltage until depletion. Size your battery to support your critical loads for the desired runtime — typically 4–24 hours depending on application criticality.
Q: Is the AL1024ULXR suitable for outdoor installations?
A: No. This is an indoor, climate-controlled enclosure supply. For outdoor or harsh-environment applications, choose a weatherproof 24VDC supply rated for the ambient temperature and humidity of your site.
Q: How long does the warranty cover?
A: The Altronix AL1024ULXR carries a Lifetime Limited Warranty, covering defects in materials and workmanship. Review the warranty documentation for exclusions and claim procedures.
Q: Does the unit support remote monitoring of AC and battery status?
A: The AL1024ULXR includes AC and battery status monitoring outputs. Integration with a management system or alarm panel requires a compatible input module or relay interface — consult the datasheet for electrical connection details.
The AL1024ULXR occupies a specific role in access control and alarm system architecture: it is the failsafe power backbone for installations where momentary supply loss triggers lockouts or missed critical events. The 10A regulated output combined with integrated battery charging and AC/battery monitoring means you eliminate one power supply and one separate charger from your Bill of Materials — a material simplification in multi-door or multi-zone deployments.
Technical Highlights:
- 10A continuous capacity (240W): Sufficient to back 4–6 electronic door strikes, 2–3 card readers, and supporting logic simultaneously. Peak power surges during strike actuation are handled cleanly without voltage sag affecting reader communication.
- Integrated battery charging with status monitoring: Real-time AC and battery status outputs allow integration with supervisory alarm panels or NVR systems. You know the moment a backup battery begins to fail, not during an outage.
- Regulated 24VDC output: Strict voltage regulation ensures downstream devices (especially card readers and logic modules) operate consistently. Unlike unregulated supplies, the AL1024ULXR maintains output within ±5% across the full 0–10A load range.
Deployment Considerations:
- Battery sizing is critical: a 7Ah SLA battery will sustain a 2A load for approximately 3 hours. A 24A battery extends runtime to 12+ hours. Audit your load profile before specifying battery capacity; undersizing is a common gotcha that leaves you with insufficient failover time.
- The AL1024ULXR is rated for climate-controlled enclosures only. If your control cabinet lacks thermostat-controlled cooling or is in an unheated garage, the unit's charging and regulation performance will degrade in temperature extremes. Plan accordingly or select a hardened alternative.
- AC input requires a dedicated 15A circuit in most installations; shared circuits with high-current HVAC or lighting loads can cause nuisance AC monitoring faults. Wire this supply on its own dedicated breaker.
This unit is the right choice for medium-scale access control systems (4–12 doors) or alarm centers where battery backup is a compliance requirement and downtime is not an option. For single-door retrofits or applications where occasional lockout is acceptable, a simpler PoE-powered reader may suffice. For large enterprise campuses, consider distributed redundancy across multiple AL1024ULXR units rather than a single point of failure.
