Altronix EFLOW4N Single Output Power Supply/Charger

Altronix EFLOW4N Single Output Power Supply/Charger

Overview

The Altronix EFLOW4N is a regulated power supply and charger designed for centralized power distribution in professional security and access control installations. Rated for 120VAC 60Hz input with selectable 12/24VDC output at 4A maximum current, the EFLOW4N delivers single primary output plus auxiliary output capability in a compact BC300 enclosure footprint. This UL Listed unit integrates battery backup supervision, fire alarm disconnect functionality, and LinQ2-ready architecture to support integrated security system deployments across mid-scale security integrations and telecom installations.

Key Features

• Dual voltage output: 12VDC or 24VDC selectable, 4A maximum rated current for flexible device compatibility
• Single primary output with auxiliary output: Supports primary load plus dedicated auxiliary circuit for monitoring or low-current auxiliary devices
• Battery backup capable: Integrated charging and supervision circuitry supports rechargeable battery backup modules for emergency power operation
• Fire alarm disconnect (FAI compliant): Automatic load disconnect on fire alarm signal detection to protect life safety circuits and meet code requirements
• AC Fail supervision: Monitors AC input status and reports power loss conditions to connected systems
• Low battery supervision: Continuous monitoring of battery voltage with fault reporting when backup power drops below operational threshold
• Battery presence supervision: Detects battery module installation status and reports missing or faulty backup batteries
• LinQ2 ready architecture: Compatible with Altronix LinQ2 networked supervision platform for remote monitoring and centralized system management
• 120VAC 60Hz input: Standard North American mains voltage operation
• BC300 enclosure: Compact, field-proven form factor for DIN rail or surface mounting in electrical cabinets and equipment racks
• UL Listed: Full UL certification ensures code compliance and insurance acceptance in commercial and institutional security deployments

Integration & Compatibility

The EFLOW4N integrates within access control, intrusion detection, and CCTV power distribution systems that require regulated 12 or 24VDC primary power with battery backup supervision. FAI (Fire Alarm Interface) compliance makes this unit suitable for installations where fire alarm systems must trigger emergency load shedding or system shutdown. The LinQ2-ready design enables the EFLOW4N to operate as a supervised node in networked power management architectures, reporting AC, battery, and supervision faults to central monitoring platforms. Compatible with standard rechargeable battery modules and support for auxiliary circuit loads makes the EFLOW4N a flexible hub for distributed security equipment power.

Ted Perry

The Altronix EFLOW4N has proven itself in field deployments where centralized power distribution must include battery backup supervision and life safety code compliance. I've specified this unit in access control retrofits and new security system installations where the combination of single primary output, auxiliary support, and fire alarm disconnect capability eliminates the need for multiple separate power supplies and relay modules.

Technical Highlights:

• Supervised power distribution: AC Fail, Low Battery, and Battery Presence supervision reporting provides real-time visibility into power system health without external monitoring hardware
• Fire alarm integration: FAI disconnect function automatically de-energizes loads on fire alarm signal, meeting life safety shutdown requirements and reducing integration complexity
• Battery-backed outputs: Auxiliary output supports battery backup operation for secondary circuits, enabling graceful degradation during power loss events

Deployment Considerations:

• Verify selectable output voltage (12 or 24VDC) matches your primary devices before installation; voltage selection is typically field-configurable
• 4A maximum current rating requires load calculation to prevent nuisance shutdowns; auxiliary circuit draws from primary output budget, so plan battery backup runtime accordingly
• LinQ2 integration enables centralized battery backup cycling and proactive fault detection across multiple EFLOW4N units in large installations, reducing service calls

For integrators managing mid-scale access control and security system expansions, the EFLOW4N delivers code-compliant power distribution with minimal additional relay or supervision infrastructure. Its compact form factor and proven reliability make it a dependable foundation for secure, supervised power distribution architectures.
