Altronix EFLOW6NBV 6A Dual-Voltage Power Supply Charger

Altronix EFLOW6NBV Power Supply and Charger

The Altronix EFLOW6NBV is a compact, dual-voltage power supply and charger designed for security integration applications requiring flexible output configurations. This unit accepts 220VAC input and provides selectable 12VDC or 24VDC output at 6 amperes, making it suitable for a range of control panels, access systems, and auxiliary equipment deployments across North American and international installations.

Overview

The EFLOW6NBV addresses the common requirement for switchable output voltage in security systems where both 12V and 24V devices coexist. The 6-ampere capacity supports moderate-load applications, including card readers, door strikes, sensors, and auxiliary monitoring circuits. The unit operates from a single 220VAC source, simplifying installation in regions with 220V mains distribution.

Key Features

• Selectable 12VDC or 24VDC output voltage configuration
• 6-ampere continuous output current rating
• 220VAC input voltage compatibility
• Compact, integrator-friendly form factor
• Charger functionality for battery backup systems
• Direct connection to standard security control panels and auxiliary loads

Output and Input Specifications

The EFLOW6NBV delivers its rated 6-ampere output across either 12VDC or 24VDC rails, allowing system designers to optimize voltage selection based on downstream device requirements and distance-to-load considerations. The 220VAC input requirement means this unit is particularly suited for European, Middle Eastern, and other 220V regions, while domestic North American 120VAC installations would require upstream voltage conversion or alternative supply selection. Operating margin and thermal design enable sustained 6A delivery without derating across typical ambient conditions.

Integration and Compatibility

The EFLOW6NBV integrates directly with security control panels that specify 12V or 24V auxiliary power inputs. Its charger function makes it suitable for systems incorporating sealed lead-acid (SLA) battery backup modules, supporting trickle-charge and float modes typical of standby power architectures. Integrators should verify control panel input voltage rating and confirm the unit's output terminals are compatible with their panel's screw-terminal or connector interface. The dual-voltage design simplifies inventory management—a single SKU can support both 12V and 24V equipment in mixed-voltage installations.

Installation Considerations

Input voltage must be confirmed as 220VAC; standard North American 120VAC circuits will not operate this unit. The EFLOW6NBV should be mounted near the control panel or battery backup module to minimize wire gauge requirements and voltage drop over the distribution run. Proper breaker or fuse protection on the 220VAC input line is mandatory. Technicians must verify output voltage selection (12V or 24V) before connecting to downstream equipment—incorrect selection risks component damage.

Battery Charging Application

When paired with backup battery systems, the EFLOW6NBV provides continuous float charging to maintain SLA battery state of charge during normal AC mains availability. The unit's charger topology supports industry-standard 12V and 24V battery string configurations. This dual-voltage capability makes the EFLOW6NBV a single-unit solution for multi-voltage backup scenarios, reducing component count and simplifying troubleshooting.

James Everett

I've evaluated the Altronix EFLOW6NBV during several regional security system deployments where 220VAC mains infrastructure was available. The dual-voltage output design is a practical advantage in mixed environments, and the 6-ampere capacity handles typical access control and auxiliary monitoring loads without oversizing the power budget.

Technical Highlights:

• Switchable Output: 12VDC or 24VDC output eliminates the need for separate 12V and 24V supplies in hybrid installations.
• 220VAC Input: Direct compatibility with international and regional mains standards, reducing the need for voltage conversion in non-North American markets.
• Charger Function: Integrated charging support for SLA backup batteries simplifies single-unit deployment in standby power architectures.

Deployment Considerations:

• Confirm 220VAC input availability before specifying this unit; North American 120VAC locations will require alternative supply selection or upstream conversion.
• Verify output voltage setting (12V or 24V) at commissioning and document the configuration in system records to prevent mismatches during future maintenance.
• Size the input branch circuit protection (breaker or fuse) in accordance with local electrical code and the unit's input current draw at 220VAC.

The EFLOW6NBV is a solid, economical choice for integrators working in 220V regions or managing multi-voltage security system architectures. The charger capability and compact footprint justify its position in standard distributor inventory for both new build and retrofit applications.
