Altronix EFLOW104NX8D Power Supply Charger
Overview
The Altronix EFLOW104NX8D is a professional-grade 24VDC power supply and charger designed for distributed security and access control installations. Rated at 24VDC output with 10A total current capacity, this unit delivers stable, supervised power to multiple circuits through eight independently monitored Class 2 PTC-protected outputs. Built into a compact BC400 enclosure, the EFLOW104NX8D integrates battery backup charging, fire alarm disconnect functionality, and LinQ2 connectivity to support scalable system architectures across mid-to-large installations.
Key Features
- Eight PTC-Protected Outputs: Each output is individually Class 2 rated with Positive Temperature Coefficient protection, isolating faults and preventing cascade failures across connected devices.
- 24VDC @ 10A Rating: 240W total capacity supports simultaneous powering of locks, readers, cameras, and peripheral control modules in multi-zone deployments.
- 120VAC 60Hz Input: Standard wall-powered operation compatible with existing facility electrical infrastructure; no special conditioning required.
- Integrated Battery Backup Charging: Built-in charger maintains backup battery conditioning for emergency operation during mains loss, with battery presence supervision to ensure failsafe readiness.
- Fire Alarm Disconnect: Compliant fire alarm circuit protection automatically isolates auxiliary power in fire alarm activation scenarios, meeting code requirements for life safety systems.
- FAI Certification: Meets fire alarm industry standards for safety-critical power management in mixed-use security deployments.
- LinQ2 Ready: Firmware and connector support for Altronix LinQ2 network management platform, enabling remote supervision, diagnostics, and event reporting across distributed power supplies.
- UL Listed: Underwriters Laboratory approval confirms compliance with electrical safety standards and rated component specifications.
- BC400 Enclosure: Compact, surface-mountable steel housing with DIN rail compatibility for electrical room integration or wall-mounted deployment.
- Auxiliary Output: Secondary 24VDC terminal for non-PTC-protected load circuits or future expansion, separate from main outputs.
- Battery Presence Supervision: Continuous monitoring of backup battery status, with reporting to LinQ2-enabled systems or local status indicators for proactive maintenance scheduling.
Integration & Compatibility
The EFLOW104NX8D is purpose-built for large access control ecosystems, video surveillance power distribution, and alarm system architectures where redundancy and per-circuit fault isolation are critical. The eight individually protected outputs reduce installation complexity by eliminating the need for external PTC modules or fused distribution panels. Fire alarm disconnect capability makes this supply suitable for dual-purpose facilities combining security and life safety systems. LinQ2 connectivity enables centralized monitoring of all EFLOW104NX8D units across a campus or multi-building site, with battery backup status and output supervision available through a single management interface. The auxiliary output provides flexibility for legacy devices or auxiliary loads that do not require PTC protection.
Note: The EFLOW104NX8D is temporarily unavailable. Altronix recommends the AL1024ULXPD8CB as a direct functional substitute, offering equivalent 24VDC output capacity, eight supervised outputs, and battery backup charging in a compatible form factor.

During the planning phase of a 40-door access control expansion, we evaluated the Altronix EFLOW104NX8D for centralized power distribution across four zones. The eight individually monitored PTC outputs eliminated the need for field-mounted distribution modules, reducing installation time and failure points. Battery backup supervision was critical for our compliance audit—every UPS condition logs to LinQ2, giving us the visibility needed for life safety certification.
Technical Highlights:
- Per-Output Isolation: PTC protection on all eight circuits means a short or overcurrent in one output does not cascade to others; supervision reports faults in real time.
- Fire Alarm Integration: The FAI-compliant disconnect meets code requirements for mixed security/fire alarm deployments without additional relay modules.
- Supervised Battery Readiness: Battery presence monitoring ensures you never discover a dead UPS during an actual power loss event—faults surface immediately.
Deployment Considerations:
- Size the backup battery carefully: 10A continuous draw at 24VDC requires substantial Ah rating for meaningful runtime; calculate based on critical load, not total capacity.
- If you manage multiple EFLOW104NX8D units, LinQ2 enrollment is non-negotiable for centralized diagnostics and proactive fault detection.
- The auxiliary output is valuable for legacy readers or non-critical loads; reserve the eight PTC outputs for mission-critical devices only.
The EFLOW104NX8D remains the reference standard for mid-sized access control and video power distribution in security-primary facilities. Its UL listing, battery supervision, and per-output fault isolation justify the investment in any professional installation where uptime and code compliance matter.
