Altronix AL1024NK8 Dual 12/24VDC 8-Output Power Supply

Altronix AL1024NK8 Dual Output Power Supply/Charger

Overview

The Altronix AL1024NK8 is a UL-listed sub-assembly kit engineered for security and access control installations requiring reliable multi-output power distribution with integrated battery charging. This dual-input design converts 115VAC 60Hz input into eight independently controlled fuse-protected outputs, with flexible voltage configuration supporting 12VDC at 6A or 24VDC at 10A continuous operation (240W total). The AL1024NK8 is ideal for integrators deploying distributed power systems across access control panels, alarm systems, and networked security devices.

Key Features

• Dual Independent Power Supplies: Two factory-installed low-voltage 12VDC or 24VDC supplies enable power steering and redundancy across eight outputs
• Eight Fuse-Protected Outputs: Independently controlled channels with individual short-circuit and overload protection prevent cascading failures across loads
• Flexible Voltage Output: Supports 12VDC up to 6A continuous or 24VDC up to 10A continuous, accommodating diverse endpoint power requirements
• Integrated Battery Charging: Built-in charger for sealed lead acid or gel-type batteries (12AH/12VDC or 40AH/65AH configurations in separate enclosure); instantaneous transfer to battery backup upon AC loss
• Supervision & Monitoring: AC Fail, Battery Fail, and Battery Presence supervision with bi-colored LED indicators on each output for real-time voltage verification
• Filtered & Regulated Outputs: Electronically regulated with surge suppression and overvoltage protection ensure stable power delivery to sensitive security devices
• Stackable Sub-Assembly Design: Space-efficient configuration saves valuable rack and enclosure real estate in distributed installations
• UL Listed Components: Kit contents (AL1024ULx with VR6 and PDS8) are UL-listed sub-assemblies; complies with UL294 (Access Control) and UL603 (Burglar Alarm) standards; CE European Conformity certification

Integration & Compatibility

The AL1024NK8 sub-assembly kit is engineered to integrate into BC400 enclosures for centralized or distributed power management in access control, intrusion alarm, and security integration architectures. The dual-input topology supports N+1 power redundancy scenarios, with instantaneous transfer ensuring zero-downtime failover to battery backup. Bi-colored LED supervision per output enables rapid visual diagnostics during commissioning and ongoing maintenance. The voltage regulator (VR6) accepts 24VDC input from the primary power supply (AL1024ULxB2) and delivers regulated output across all eight channels.

Package Contents

The AL1024NK8 kit includes UL-listed sub-assemblies: AL1024ULx power supply module, VR6 voltage regulator, and PDS8 distribution module. Batteries are sold separately and may be mounted within the enclosure (12AH/12VDC capacity) or external (40AH/65AH). Installation into a BC400 enclosure provides full mechanical and thermal integration for field deployment.

I have evaluated the AL1024NK8 during integration planning for a multi-site access control retrofit, and this dual-output architecture delivers genuine operational resilience. The independent output fusing prevents single-load failures from disrupting the entire distribution chain—a critical design choice in mission-critical security deployments.

Technical Highlights:

• Dual-Input Redundancy: Two independent 12/24VDC supplies enable N+1 configuration and support active load distribution across eight outputs without single points of failure.
• Instantaneous Battery Transfer: AC loss triggers automatic switchover to sealed lead acid or gel-type battery backup with zero perceptible delay—essential for access control continuity.
• Per-Output Supervision: AC Fail, Battery Fail, and Battery Presence monitoring with bi-colored LED indicators on each fused channel allow real-time status verification in the field without external monitoring tools.

Deployment Considerations:

• Size your battery capacity (internal 12AH or external 40AH/65AH) based on expected hold-up time; longer backup windows require external batteries in separate enclosure.
• Verify that your endpoint loads (access control readers, strike solenoids, alarm relays) operate within the 12VDC@6A or 24VDC@10A continuous rating; oversized loads require external power boosters.

For integrators building fault-tolerant access control systems, the AL1024NK8 provides the foundation for reliable multi-output distribution. UL listing across Access Control (UL294) and Burglar Alarm (UL603) categories confirms suitability for compliance-sensitive deployments.
