Altronix EFLOW4N8V 12/24VDC 4A 8-Output Power Supply

Altronix EFLOW4N8V Power Supply/Charger

Overview

The Altronix EFLOW4N8V is a dual-voltage (12/24VDC) power supply and battery charger designed for distributed security and life safety installations. Operating from 120VAC 60Hz input, this unit delivers 4A maximum current across 8 individually fused outputs, making it suitable for multi-channel access control, alarm monitoring, and emergency lighting applications. The EFLOW4N8V integrates battery backup capability with fire alarm disconnect functionality, providing both power distribution and supervised charging in a compact DIN-rail or wall-mountable form factor.

Key Features

• Dual Output Voltage: Configurable 12VDC or 24VDC operation to support legacy and modern 24V security devices
• 4A Total Output Current: Sufficient capacity for distributed power loads in medium-scale integrated systems
• 8 Individually Fused Outputs: Circuit-level protection isolates faults and reduces mean-time-to-repair (MTTR)
• 120VAC 60Hz Input: Standard North American mains compatibility with straightforward utility connection
• Battery Backup Charging: Integrated charger maintains auxiliary battery for system continuity during AC mains loss
• Fire Alarm Disconnect: Compliant with fire safety code requirements; enables safe isolation of non-critical loads during emergency conditions
• AC Fail Supervision: Real-time monitoring detects mains loss and triggers system notifications
• Low Battery Supervision: Warns operators of declining backup battery voltage before capacity exhaustion
• Battery Presence Detection: Confirms auxiliary battery installation and connectivity to prevent unnotified system degradation
• UL Listed: Third-party certification confirms compliance with electrical and safety standards for commercial security installations

Integration & Compatibility

The EFLOW4N8V supplies both 12VDC and 24VDC outputs, accommodating mixed-voltage device ecosystems common in retrofit and multi-vendor deployments. Supervision functions—AC fail, low battery, and battery presence detection—report to connected control panels via standard alarm contact closures or hardwired inputs, simplifying integration into existing management platforms without proprietary software licensing. The 8-output configuration allows independent distribution to multiple devices such as door controllers, card readers, auxiliary locks, or remote modules, each protected by individual fuses to maintain partial system operation during localized circuit faults.

Battery Backup & Fire Safety

Battery backup capability preserves critical access control and emergency communication during mains outages, extending system uptime through transitions and brief power events. The fire alarm disconnect feature ensures the power supply can be de-energized or load-shed during fire alarms, supporting code-compliant emergency egress scenarios. Combined with low battery and AC fail supervision, the EFLOW4N8V enables proactive monitoring of power infrastructure health and automatic failover logic.

During recent system deployments, the Altronix EFLOW4N8V has proven reliable for mid-scale distributed access and monitoring applications. Its 8-output architecture and integrated supervision make it a practical choice for integrators managing mixed 12V and 24V device inventories without requiring separate power plants per voltage class. The EFLOW4N8V delivers straightforward power distribution with built-in resilience.

Technical Highlights:

• Fused Output Isolation: Individual fuses on all 8 outputs minimize fault propagation and reduce troubleshooting burden in multi-device environments
• Battery Charging & Monitoring: Integrated charger with presence and voltage supervision prevents silent battery failure and extends backup runtime confidence
• Fire Code Compliance: Fire alarm disconnect and supervision architecture align with life safety regulations without requiring retrofit logic modules
• Dual Voltage Output: 12VDC and 24VDC selectable operation simplifies inventory and supports heterogeneous device networks

Deployment Considerations:

• Verify auxiliary battery voltage and chemistry compatibility before integration; consult battery specifications for charge current limits to avoid overcharge
• Size backup battery capacity based on load profile and desired uptime; 4A output headroom accommodates moderate loads but does not guarantee extended outage duration without appropriately rated battery
• Test fire alarm disconnect wiring during commissioning to confirm load-shed behavior meets local code inspections and emergency response procedures
• Monitor AC fail and low battery notifications continuously; configure alerting rules to dispatch maintenance before battery depletion during unplanned mains loss

For integrators deploying distributed access control or emergency lighting in commercial and institutional facilities, the EFLOW4N8V offers a cost-effective, code-compliant platform for reliable power distribution and supervised battery charging without excessive complexity or proprietary firmware dependencies.
