Altronix EFLOW102NA8D 8-Output Access Power Controller

Altronix EFLOW102NA8D Access Power Controller with Power Supply and Charger

Overview

The Altronix EFLOW102NA8D is an access power controller and integrated power supply/charger designed for security integrators and access control system installers. This unit combines regulated 12VDC power distribution with battery charging capability in a single enclosure, providing reliable power management for access control devices, door locks, and auxiliary equipment. The EFLOW102NA8D is housed in a BC400 enclosure and accepts 115VAC input, making it suitable for standard North American facility installations.

Key Features

• 8 PTC Class 2 Relay Outputs: Provides eight independently controlled relay outputs for door locks, magnetic locks, and access control accessories with built-in overcurrent protection via PTC (positive temperature coefficient) devices
• 12VDC Power Supply with Integrated Charger: Supplies 12VDC output with onboard battery charging circuitry for seamless backup power integration
• 6A Maximum Current Rating: Delivers up to 6A at 12VDC for powering multiple access devices simultaneously
• Auxiliary Output: Dedicated auxiliary output for controlling ancillary systems or signaling devices
• FAI Support: Integrated Fault Alerting Interface (FAI) for system supervision and fault detection reporting
• 115VAC Input: Standard wall power input for North American installations without external transformers
• UL Listed and CE Approved: Meets UL safety standards and CE compliance requirements for international deployment
• BC400 Enclosure: Compact, wall-mounted steel enclosure designed for indoor installation in access control cabinets and security rooms

Integration and Compatibility

The EFLOW102NA8D integrates into access control systems requiring centralized power distribution and battery backup. The eight PTC relay outputs accommodate standard 12VDC door locks, magnetic locks, strike plates, and request-to-exit buttons. The integrated charger maintains connected backup batteries in ready state, ensuring continuity of access control during utility power loss. The FAI supervision output enables real-time monitoring of system health, allowing control panels to detect power supply faults or output failures and trigger appropriate alerts to the security operations center.

Technical Specifications

Input voltage operates at 115VAC. Output voltage is regulated at 12VDC with a maximum current rating of 6A per the specifications. The unit provides 8 PTC Class 2 relay outputs plus one auxiliary output. UL Listed and CE marked certifications are included. The device is designed for installation in standard BC400 enclosures suitable for wall-mount or cabinet integration.

I've specified the Altronix EFLOW102NA8D in several multi-door access control deployments where centralized power management and battery backup were critical. This unit addresses a common integration challenge: coordinating multiple relay outputs while maintaining supervision and ensuring backup power availability during outages. The EFLOW102NA8D consolidates these functions into a single, UL-listed enclosure.

Technical Highlights:

• PTC Overcurrent Protection: Each of the 8 relay outputs includes integrated PTC devices that limit fault current automatically, eliminating the need for external fuses and reducing nuisance disconnections from transient spikes
• Battery Charging Integration: The onboard charger accepts auxiliary battery connections, maintaining them in float charge during normal operation and delivering power during AC loss without external relay logic
• FAI Supervision: The Fault Alerting Interface output enables the control panel to monitor supply voltage and output availability, supporting system-level supervision and redundancy decision-making

Deployment Considerations:

• Confirm backup battery specifications and charging requirements before connecting to the EFLOW102NA8D charger input; oversizing or incompatible chemistry can affect charger performance
• Plan relay output assignments early, as each of the 8 outputs serves a distinct access point or accessory; document assignment to simplify troubleshooting and future modifications
• Mount the BC400 enclosure in a climate-controlled space when possible; extended operation outside rated temperature ranges may affect charger accuracy and power supply regulation

For access control systems requiring reliable, supervised power distribution across multiple doors or zones, the EFLOW102NA8D represents a standard choice among integrators. Its combination of relay density, battery charging, and supervision makes it suitable for small to mid-sized deployments where centralized power management reduces complexity and improves system resilience.
