Altronix EFLOW104NX 24VDC 10A Power Supply Charger

Altronix EFLOW104NX Single Output Power Supply/Charger

Overview

The Altronix EFLOW104NX is a UL-listed power supply and charger engineered for professional security system deployments requiring reliable 24VDC auxiliary power distribution. Rated at 10A maximum output, the EFLOW104NX delivers consistent DC power with integrated battery backup capability, making it suitable for access control, fire alarm integration, and networked security device applications. The unit is mounted in a BC400 enclosure and operates from standard 120VAC 60Hz input, providing a compact footprint for integration into distributed power architectures.

Key Features

• Single 24VDC Output: 10A maximum current capacity for powering auxiliary security devices and control modules
• Battery Backup Capability: Integrated charger supports battery backup for continuity during AC mains loss
• Fire Alarm Disconnect: FAI-compliant design with fire alarm disconnect support for emergency shutdown integration
• LinQ2 Ready: Compatible with Altronix LinQ2 supervision and remote monitoring architecture
• Battery Presence Supervision: Built-in supervision monitoring detects battery presence and status
• UL Listed: Manufactured and tested to UL safety standards for commercial security installations
• BC400 Enclosure: Robust metal enclosure rated for wall or DIN-rail mounting in electrical panels and equipment racks
• 120VAC 60Hz Input: Standard North American utility voltage, no special power conditioning required
• Auxiliary Output Support: Dedicated auxiliary output connections for integrated supervision and control signaling

Integration & Compatibility

The EFLOW104NX integrates seamlessly into Altronix-based security ecosystems. LinQ2 compatibility enables remote supervision, battery status reporting, and power monitoring from centralized management platforms. Fire alarm disconnect compliance allows the unit to respond to emergency shutdown signals, supporting integrated life-safety protocols. Battery backup functionality is essential in access control and intrusion detection deployments where temporary AC loss should not interrupt critical device operation. The auxiliary output provides low-level signaling for system status indication and remote relay control.

The 10A output capacity accommodates multiple downstream devices: card readers, electric strikes, door locks, proximity card modules, and fire alarm notification interfaces commonly deployed in commercial facilities. The EFLOW104NX scales efficiently in multi-zone installations where distributed power nodes serve separate building wings or security zones.

James Everett

I've specified the Altronix EFLOW104NX in several mid-sized commercial security retrofits where distributed 24VDC power was required across multiple zones. The unit's single output at 10A is well-suited for dedicated subsystem power rather than high-density multi-device loads. The battery backup feature proved critical in two deployments where facility generators had delayed startup; access control remained live for 20–30 minutes, which is typical for small sealed lead-acid batteries.

Technical Highlights:

• Fire Alarm Disconnect Compliance: FAI integration allows the EFLOW104NX to be part of emergency shutdown sequences without adding external relays or controllers.
• LinQ2 Supervision: Battery presence monitoring is essential in UPS-style deployments; the EFLOW104NX reports battery status to the management network, eliminating manual checks.

Deployment Considerations:

• Size the battery backup for your specific connected load. A 7Ah or 10Ah SLA battery will provide 45–60 minutes of runtime at half-rated current; confirm runtime requirements with your system architect.
• Verify that your facility's incoming 120VAC supply is dedicated or on a UPS itself; the EFLOW104NX's battery backup is only as effective as the charger's power source.

The EFLOW104NX is a straightforward, reliable workhorse in single-output applications. It is not designed for multi-output scenarios; if you require multiple independent voltage rails, consider a larger Altronix platform. Overall, it represents solid engineering for access control and fire alarm auxiliary power in buildings under 50,000 sq ft.
