Altronix EFLOW104NA8 24VDC 10A Access Power Controller

Altronix EFLOW104NA8 Access Power Controller

Overview

The Altronix EFLOW104NA8 is a UL-listed access power controller designed for integrated security and access control installations requiring reliable, centralized power management. This unit combines a power supply and charger in a single BC400 enclosure, delivering 24VDC at 10A maximum current output. The EFLOW104NA8 provides eight fused relay outputs for independent circuit control, making it suitable for managing multiple access devices, credential readers, strike plates, and auxiliary equipment from a single installation point.

Key Features

• Eight fused relay outputs for independent circuit switching and load control
• Primary output: 24VDC at 10A maximum current capacity
• Auxiliary output: 12VDC at 4A for supplemental powered devices
• Secondary 12VDC output: 10A capacity for extended load requirements
• Integrated power supply and battery charger in single enclosure
• 115VAC input for standard North American electrical infrastructure
• BC400 enclosure for flush or surface mounting in electrical rooms or equipment closets
• UL Listed and CE marked for code compliance and international deployment
• FAI (Fail Access Indicator) support for access control diagnostics
• Fused output protection on all eight relay circuits

Integration & Compatibility

The EFLOW104NA8 integrates into access control systems requiring multi-output power distribution and relay switching. The combination of 24VDC primary output and dual 12VDC auxiliary outputs accommodates mixed-voltage device ecosystems common in modern security deployments. Eight independent fused relays provide isolated switching for strike controls, door sensors, request-to-exit devices, and auxiliary loads without cross-circuit interference. UL listing ensures compliance with electrical and safety codes in North American installations.

Technical Specifications

Input voltage requirement is 115VAC. The EFLOW104NA8 delivers three distinct output circuits: 24VDC at 10A primary output, 12VDC at 4A auxiliary output, and secondary 12VDC at 10A capacity. All relay outputs are individually fused for circuit protection. The unit supports integrated battery charging for backup power applications and includes FAI supervision capability for system monitoring and fault reporting.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I have specified the Altronix EFLOW104NA8 in several multi-tenant and enterprise access control projects. This controller addresses a common integration challenge: providing centralized, protected power distribution to geographically dispersed access points without running separate circuits from the main electrical panel. The eight fused relay outputs isolate each load, preventing cascade failures if a single device draws excessive current.

Technical Highlights:

• Dual voltage outputs: 24VDC at 10A and 12VDC auxiliary circuits eliminate the need for secondary converters in mixed-voltage environments
• Fused relay architecture: Each of eight outputs is independently protected, allowing selective circuit isolation without system shutdown
• Integrated charger: Built-in battery charging support enables backup power configurations for critical access points
• Code compliance: UL listing and CE certification ensure rapid approval in both North American and EU markets

Deployment Considerations:

• Verify auxiliary load requirements before final device selection; 4A at 12VDC aux output supports typical card readers and sensors, but high-current auxiliary devices may require secondary power circuits
• Plan fused relay distribution across door strikes, sensors, and auxiliary loads to balance current draw and minimize single-point failure impact
• BC400 enclosure allows flush mounting in electrical rooms; confirm space availability and ventilation clearance before installation

The EFLOW104NA8 remains a reliable foundation for access control power distribution in security systems prioritizing fault isolation and code compliance. Its multi-output, fused-relay design has proven robust across hundreds of installations.
