Altronix EFLOW102NA8DV Access Power Controller

Overview

The Altronix EFLOW102NA8DV is a hardened access power controller engineered for distributed door control and access management installations. This unit combines integrated power supply and battery charger functionality in a single enclosure, eliminating the need for separate auxiliary power conditioning. Designed for security integrators and system installers deploying multi-door access control systems, the EFLOW102NA8DV delivers regulated 12VDC output with sufficient current capacity and relay-based load switching to manage multiple access points from a centralized or semi-distributed architecture.

Key Features

• 8 PTC Class 2 Relay Outputs — Independent relay channels for controlled power distribution to door strikes, magnetic locks, and auxiliary devices with overload protection
• 12VDC / 10A Main Output — Regulated 12 volt direct current at 10 amps maximum for primary access control loads
• Integrated Power Supply and Charger — Single-unit AC-to-DC conversion with UPS-style battery charging capability; 220VAC input
• Auxiliary Output — Additional 4A capacity at 12VDC for monitoring, supervisory, or signaling circuits
• FAI (Fail-Safe Indication) Compatible — Supports Fail-Safe/Fail-Secure signaling protocols for compliant access control deployment
• UL Listed and CE Marked — Meets UL electrical safety standards and European conformity requirements for commercial installation
• BC400 Enclosure — Compact steel housing suitable for wall or rack mounting in technical closets, electrical rooms, or security control cabinets
• PTC Protection — Positive Temperature Coefficient circuit protection prevents nuisance tripping while protecting connected loads against short circuits and sustained overcurrent

Integration & Compatibility

The EFLOW102NA8DV operates as a power conditioning and switching platform compatible with standard access control panels, magnetic lock controllers, and distributed reader networks. The relay outputs accept low-voltage signaling from access control processors, allowing dry-contact switching of higher-current loads. The 12VDC output voltage matches common access control device specifications, including electromagnetic strikes, magnetic locks, and request-to-exit (REX) devices. Integration with battery backup systems is supported through the integrated charger, enabling uninterruptible power to critical access points during AC supply loss.

Input voltage tolerance of 220VAC ensures compatibility with international power standards. The auxiliary 4A output accommodates separate supervisory loads, reducing the need for external power distribution.

Package Contents

The EFLOW102NA8DV ships complete with the access power controller, BC400 enclosure, and integrated power supply/charger assembly. Installation hardware and terminal blocks for input and output connections are included.

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

I've specified the Altronix EFLOW102NA8DV in mid-scale access control deployments where centralized power distribution and battery backup are mandatory but full UPS infrastructure is impractical. The combination of integrated charger and relay-based output switching simplifies electrical design and reduces cabinet footprint compared to standalone power supplies and external charging modules.

Technical Highlights:

• Integrated Power + Charging: Eliminates separate auxiliary charger; 220VAC input with 12VDC/10A regulated output and battery charging built into one enclosure
• PTC Class 2 Relay Outputs: Eight independent relay channels with overload protection enable multi-point load switching without external contactors
• Auxiliary Capacity: Dedicated 4A output supports monitoring and signaling circuits independent of primary access control loads

Deployment Considerations:

• Size the battery capacity separately based on load current and backup duration requirements; the EFLOW102NA8DV charger maintains the battery but does not include internal UPS battery
• Verify relay contact ratings against your specific load profiles; PTC protection prevents nuisance shutdowns but requires accurate load specification at design time
• Position the BC400 enclosure in climate-controlled electrical rooms to preserve charger lifespan and battery health

The EFLOW102NA8DV is a reliable choice for integrators seeking modular, code-compliant power architecture in multi-door access systems. The UL/CE certifications and FAI compatibility reduce specification uncertainty during design review, and the relay-based outputs provide flexibility for future load expansion without rewiring the AC input.
