Altronix AL1024XB2V 24VDC Power Supply Single Fused Output
The Altronix AL1024XB2V is a compact 24VDC power supply and battery charger designed for small-to-medium security installations requiring reliable single-output DC power distribution with integrated backup capability. This unit operates from 220VAC input (198–256VAC working range), delivering 24VDC at 8A continuous output with 10A capacity during alarm state. The AL1024XB2V supports sealed lead acid or gel-type backup batteries (sold separately), making it a practical choice for access control systems, small security camera installations, and gate operators where power interruption poses a deployment risk.
Key Features
- Single Fused 24VDC Output: Rated for 8A continuous and 10A during alarm state—sufficient to power multiple door locks, card readers, or a small IP camera array without exceeding power budgets on typical installations.
- 220VAC Input with Wide Operating Range: Accepts 198–256VAC, accommodating international and regional voltage variations without requiring a separate isolation transformer in most cases.
- Integrated Battery Charging: Built-in charger maintains sealed lead acid or gel-type backup batteries, enabling automatic UPS operation when AC mains fail. Eliminates the need for a separate charger module in compact installations.
- AC Failure Supervision: Form C relay contact signals loss of AC input, allowing integration with building automation or security control systems for event logging or alarm escalation.
- Battery Presence and Low Battery Supervision: Dedicated Form C contacts monitor battery status and voltage, triggering alerts before capacity is exhausted—critical for preventing unplanned downtime during extended outages.
- Compact Board Form Factor: 8.4" × 4.5" × 1.9" dimensions fit into standard electrical enclosures without requiring dedicated cabinet space, reducing installation footprint in retrofit or space-constrained environments.
- Operating Temperature Range 0°C to 49°C: Suitable for climate-controlled indoor installations but not for outdoor or unheated enclosures; verify ambient conditions before deployment in variable-temperature spaces.
- Lifetime Limited Warranty: Manufacturer backs the unit with a lifetime limited warranty, reducing long-term support costs for stable, low-failure deployments.
Integration and Compatibility
The AL1024XB2V integrates into access control and UPS architectures where standard 24VDC loads require battery backup. The single output and fused design simplify circuit protection; however, installations requiring multiple independent outputs or zone-based power distribution should consider larger Altronix models in the XB series. Form C relay contacts enable integration with legacy security panels, building management systems, and SCADA platforms that monitor AC and battery status. Confirm battery type (sealed lead acid or gel) compatibility with your existing UPS infrastructure before ordering.
When to Choose a Different Model
If your installation requires multiple independently fused outputs, redundant power supplies, or outputs exceeding 10A capacity, evaluate higher-capacity Altronix power supply variants. For installations without battery backup requirements, a simpler non-charger 24VDC power supply may reduce cost. For outdoor or unheated enclosures, verify temperature rating compatibility or choose units rated for extended operating ranges.
Frequently Asked Questions
Q: What battery types does the AL1024XB2V support?
A: The unit supports sealed lead acid and gel-type backup batteries. Lithium or AGM batteries are not specified in the manufacturer documentation—confirm compatibility with the battery supplier before purchase.
Q: Does the AL1024XB2V provide redundancy or failover to a second supply?
A: No. This is a single-supply unit with battery backup only. For redundant AC-to-DC power, consider dual-supply configurations using separate Altronix units and a combining module.
Q: What is the warranty period?
A: Lifetime Limited Warranty from the manufacturer, covering defects in materials and workmanship under normal operating conditions.
Q: Can I use the AL1024XB2V outdoors?
A: No. Operating temperature range is 0°C to 49°C, and the unit is designed for indoor enclosure mounting. Outdoor installations require weatherproof cabinetry and thermal management.
Q: How much output power is available during battery-backed alarm operation?
A: 10A at 24VDC (240W) during alarm state, compared to 8A continuous. This boost capacity supports transient loads like door strikes or siren activation.
Q: Do I need to configure any settings, or is it plug-and-play?
A: The AL1024XB2V requires no configuration. Connect 220VAC input, wire 24VDC output loads and battery, and configure the relay contact supervision in your control panel.

The Altronix AL1024XB2V hits a specific niche: compact, no-frills power backup for access control and small camera systems where outage protection matters but space is tight. The 8A continuous / 10A alarm split is practical—you'll run your steady-state loads on the 8A budget and rely on the 10A capacity for momentary spikes (door strikes, siren relay activation). The integrated battery charger eliminates a separate module, and the Form C supervision contacts give you visibility into AC loss and battery health, which any professional deployment requires.
Technical Highlights:
- 220VAC Input with 198–256VAC Tolerance: The wide operating window means this unit adapts to regional voltage sag, surge, and frequency variation without auxiliary regulation. You don't need a separate AVR on most installations, reducing BOM and footprint.
- Integrated Battery Charger for Sealed Lead Acid or Gel: Floating-charge architecture keeps batteries topped off during normal operation and delivers full charging current if capacity drops. No external charger to procure or configure—one less failure point in the field.
- Three Form C Relay Outputs (AC Fail, Battery Present, Low Battery): These contacts hook directly into your security panel or BMS, enabling event logging, email alerts, or automatic load shedding if battery voltage drops below threshold. This is not a dumb power box; it's supervising its own state.
Deployment Considerations:
- Single Output, Single Fuse—No Zone Isolation: All connected loads share one fuse. If a short occurs downstream, you lose everything. For multi-zone access control, you'll need a larger Altronix XB model with separate fused outputs, or manage risk through load segregation upstream.
- Temperature Envelope 0–49°C Only: This is an indoor, climate-controlled unit. If your electrical enclosure sees seasonal extremes (unheated garage, sunbaked utility closet), the AL1024XB2V will throttle or shut down. Verify your site conditions before specifying.
- Battery Sizing Not Included: The charger works with any lead-acid or gel battery you bring, but *you* must size it. Undersize, and a 2-hour power loss drains it flat. Oversize, and the charger may take 12+ hours to top off. Know your load duration requirement before ordering the battery.
Deploy the AL1024XB2V where you need predictable, compact 24VDC backup for a single access control circuit or small IP camera ring—a building lobby with two card readers and a strike, or a warehouse loading dock with one outdoor camera and a gate operator. It will keep power on and signal the control room when AC fails. Don't stretch it beyond 8A continuous or into multi-zone scenarios; that's not what this design does.
