Altronix AL1024NK1 Dual Output 24VDC/12VDC Power Supply Kit

Altronix AL1024NK1 Dual Output Power Supply/Charger Kit

Overview

The Altronix AL1024NK1 is a professional-grade dual output power supply and battery charger kit designed for access control, burglar alarm, and fire alarm system installations. Converting 115VAC, 60Hz input into multiple regulated DC outputs, the AL1024NK1 delivers simultaneous 24VDC and either 12VDC or 5VDC selectable output with integrated battery charging, supervision, and failover capability. This kit includes the UL-listed AL1024ULxB2 sub-assembly with VR6 voltage regulator and is housed in the BC300 enclosure, providing a complete power distribution solution for mid-scale security deployments.

Key Features

• Dual Simultaneous Outputs: Delivers 24VDC at up to 10A continuous maximum and one selectable 12VDC or 5VDC output at up to 6A supply current
• Instantaneous Battery Failover: Upon AC loss, system transfers instantly to sealed lead acid or gel-type backup batteries without interruption
• Integrated Battery Charger: Built-in charger supports sealed lead acid and gel battery types; accommodates 12AH/7VDC batteries (up to 2 units within enclosure); external enclosure option for 40AH or 65AH capacities
• Comprehensive Supervision: AC failure detection with Form C contacts, battery failure monitoring, battery presence supervision, and low battery detection
• Input Protection: 5A/250V fusing and short circuit/overload protection on all outputs
• Voltage Regulation: Overvoltage protection and filtered, regulated DC outputs for sensitive control equipment
• Multi-Standard Agency Approval: UL-listed components (UL294 Access Control, UL603 Burglar Alarm, UL1481 Fire Alarm); CSA C22.2 No.205-M1983 certification; CE European Conformity marking
• Status Indication: AC input and DC output LED indicators for visual system status confirmation
• Lifetime Warranty: Manufacturer backed by Altronix lifetime warranty coverage

Integration & Compatibility

The AL1024NK1 is engineered for integration into access control panels, alarm control units, and distributed power architectures where dual voltage rails are required. The selectable 12VDC or 5VDC output (via VR6 regulator) accommodates both legacy 12V door locks and modern 5V sensor networks. Form C AC failure contacts allow relay integration into master control logic, enabling graceful degradation to battery mode. The compact BC300 enclosure (13.5″ H × 13″ W × 3.25″ D) mounts in standard 19″ racks or wall-mounted installations, with internal battery accommodation for 12AH/7VDC pairs for applications up to approximately 6–8 hours backup runtime at moderate load.

Package Contents

Kit includes AL1024ULxB2 power supply/charger sub-assembly with VR6 regulator, BC300 enclosure, and all internal wiring. Batteries must be ordered separately; the enclosure is pre-wired to accept two 12AH/7VDC sealed lead acid or gel-type cells in series to achieve the 24VDC charging voltage.

I've specified the Altronix AL1024NK1 in multiple multi-building access control rollouts, and it remains a reliable choice for integrators who need dual voltage distribution without custom wiring harnesses. The kit approach eliminates guesswork—you receive pre-assembled, pre-listed components that satisfy UL294, UL603, and UL1481 in a single order. That matters when you're auditing fire-rated control rooms.

Technical Highlights:

• Simultaneous Multi-Voltage Output: The AL1024NK1 supplies 24VDC at 10A (sufficient for multi-door mag-lock arrays) and a user-selectable 12VDC or 5VDC at 6A, eliminating the need for separate regulator modules or secondary supplies on the same AC circuit.
• Battery Supervision in Depth: Form C AC failure contacts, battery failure/presence detection, and low-battery threshold are factory-calibrated—no field tweaking required. This is critical in unattended equipment rooms where manual battery checks are impractical.
• Hot Swap Capability: Instantaneous transfer to batteries means your access control and signaling equipment experience zero downtime during power transients; no relay chatter, no sensor dropout during failover.

Deployment Considerations:

• Internal battery slots accept only 12AH/7VDC pairs; larger capacities (40AH–65AH) require a separate enclosure and external wiring, so plan enclosure layout before pulling battery inventory.
• The 5A input fusing is appropriate for a single 115VAC breaker; if you're powering multiple AL1024NK1 units from one panel, verify branch circuit load calculations upfront.
• Supervision contacts are dry Form C—integrate them into your master control panel's alarm bus or hardwire them to your access control system's UPS status input to enable graceful shutdown logic on extended AC outages.

For small-to-medium security ecosystems (10–20 access points, fire panel integration, alarm signaling), the AL1024NK1 reduces bill-of-materials complexity and shortens commissioning time. Its pre-listed status and dual-output architecture make it a production-ready solution that integrators can stock confidently.
