Altronix AL1024X220 Power Supply/Charger
Overview
The Altronix AL1024X220 is a 24VDC power supply and battery charger designed for security installations requiring reliable DC power conversion and battery backup from 220VAC international mains input. This single fused output model delivers 10A maximum continuous output at 24VDC, making it suitable for medium-load distributed power architectures in access control, CCTV, and alarm system deployments across European and international markets.
The unit operates across a 198VAC–256VAC input range at 50/60Hz, accommodating typical regional voltage variations. Input-side protection is provided by a 5A/250V fuse. The AL1024X220 features an integrated sealed lead acid or gel-type battery charger with instantaneous automatic transfer to battery backup, eliminating power loss during AC supply interruptions—critical for systems requiring uninterrupted operation.
Key Features
- Single fused output: 24VDC @ 10A maximum, with one main output branch for simplified wiring in single-load or primary power architectures
- 220VAC input: 198–256VAC operating range, 50/60Hz, accommodates international mains standards with 5A/250V primary fusing
- Built-in battery charger: Designed for sealed lead acid or gel-type batteries; automatic instantaneous transfer to battery power on AC mains loss
- Battery monitoring: AC Fail supervision, Battery Fail detection, and Battery Presence indication for system oversight and alarm reporting
- Short-circuit and overload protection: Safeguards connected loads from fault conditions
- CE European Conformity: Compliant with European electrical and safety directives for market-ready deployment
- Enclosure options: Available in grey or red powder-coat finish for visual site identification or aesthetic integration
- Compact form factor: 15.5" × 12" × 4.5" (393.7 × 304.8 × 114.3 mm) fits standard electrical cabinets and wall-mounted installations
- Lifetime Warranty: Full manufacturer coverage, reducing lifecycle cost and supporting long-term system reliability
Integration & Deployment Considerations
The AL1024X220 is the entry-level configuration in the AL1024x220 series, ideal for single-branch power distribution or primary supply feeds. Organizations requiring multi-output or higher-granularity circuit protection should evaluate the 4, 8, or 16-output variants (PD4, PD8, PD16 configurations) available within the same product line. All series variants share identical input voltage, output voltage, and maximum current specifications, enabling standardized procurement and field interchangeability of charger modules where battery backup capacity scaling is planned.
Battery sizing and configuration must be calculated based on system load, backup duration, and battery chemistry. Consult Altronix technical support or your integrator for battery selection guidance. The instantaneous transfer mechanism ensures no power loss to critical loads during mains failure—typical for access control lock power and alarm sensor circuits.
Electrical Specifications
Output voltage is regulated 24VDC. Total current capacity is 10A maximum. The unit is designed for 50/60Hz operation across the full 198–256VAC input window. Temperature range and humidity ratings are available in detailed technical documentation from the manufacturer. Weight is 9.25 lbs (4.2 kg) product, 11.55 lbs (5.24 kg) shipping.
Ted PerryPerspective based on aggregated and affiliated engineering team experience.
I've specified the Altronix AL1024X220 in multi-site European deployments where 220VAC mains is standard and battery backup is non-negotiable for access control continuity. The single fused output keeps wiring simple for primary power feeds, and the integrated charger eliminates the need for standalone battery management hardware.
Technical Highlights:
- Wide input tolerance: 198–256VAC operating window absorbs regional mains fluctuations without load loss, reducing nuisance power cycling
- Instantaneous battery transfer: Automatic switchover on AC fail ensures zero-dropout power to locks and alarm sensors; no external relay logic required
- Supervision outputs: AC Fail, Battery Fail, and Battery Presence signals integrate with building management or alarm panels for centralized monitoring and alerting
Deployment Considerations:
- Battery chemistry matters—confirm the charger voltage setting matches your sealed lead acid or gel battery type before installation to prevent overcharging or undercharging
- 10A maximum is suitable for single primary feeds (e.g. a controlled door set) or smaller distributed loads; multi-door or multi-zone systems should use PD8 or PD16 variants for circuit segregation and redundancy
The lifetime warranty and CE marking give confidence in long-term field performance. For 220VAC installations requiring battery-backed 24VDC power with integrated supervision, the AL1024X220 is a straightforward, field-proven choice.
