Altronix TANGO1B PoE Board Supply Lithium Backup

Altronix TANGO1B PoE-Driven Power Supply with Lithium Battery Backup Board

Overview

The Altronix TANGO1B is a compact, board-level power supply engineered for security integrators and IT managers who require reliable backup power in access control, surveillance, and IP network infrastructure deployments. This PoE-driven unit combines power conditioning with integrated lithium battery backup capability, eliminating the need for separate UPS modules in space-constrained installations. The TANGO1B is designed for direct integration into enclosures, rack systems, and distributed network architectures where redundancy and uptime are critical.

Key Features

• PoE-Powered Architecture: Receives power directly from PoE infrastructure, reducing dependency on dedicated AC circuits and simplifying deployment in remote or difficult-to-reach locations.
• Integrated Lithium Battery Backup: Onboard battery provides emergency power to connected loads during AC loss or PoE supply interruption, ensuring continuous operation of critical systems.
• Board Form Factor: Compact module design allows integration into OEM enclosures, custom control systems, and retrofit installations without requiring separate external power supplies.
• PoE Input Compliance: Accepts standard PoE input power, compatible with IEEE 802.3at/af-class infrastructure and enterprise-grade network switches.
• Regulated Output: Delivers stable, filtered DC power suitable for powering IP cameras, access control readers, door locks, intercoms, and supplementary network devices.
• Compact Footprint: Board-level construction minimizes space overhead, enabling integration into wall plates, junction boxes, and distributed power node architectures.

Integration and Deployment Considerations

The TANGO1B is well-suited for security integrators designing redundant power distribution across multiple sites. Its PoE input eliminates the need for independent AC power drops at each endpoint, reducing installation labor and infrastructure costs. The integrated lithium battery backup ensures that critical access control checkpoints, emergency intercoms, and surveillance equipment remain operational during utility outages—a requirement in many commercial and institutional environments.

When deployed in distributed architectures, the TANGO1B supports staged failover strategies. Multiple units can be daisy-chained or networked through standard management protocols, allowing centralized monitoring of battery health, output voltage, and load current. This capability is particularly valuable in multi-floor office buildings, campus environments, and critical infrastructure facilities where power availability is monitored in real time.

Battery Backup and Runtime

The integrated lithium battery is specifically selected for long shelf life, predictable discharge characteristics, and compatibility with the board's charging and monitoring electronics. Unlike lead-acid alternatives, lithium chemistry offers lighter weight and more compact dimensions, making the TANGO1B suitable for overhead installations and space-limited enclosures. Battery health is managed through integrated charge control circuitry, extending service life and reducing unexpected failures.

James Everett

I've specified the TANGO1B in several access control deployments where traditional UPS cabinets were impractical. The board form factor and PoE input architecture eliminate installation bottlenecks and simplify network integration. For integrators managing multi-building campuses, the TANGO1B's modular design allows distributed backup power without dedicated utility infrastructure at each node.

Technical Highlights:

• PoE Integration: The TANGO1B accepts PoE input directly from network infrastructure, eliminating separate AC power distribution to remote endpoints.
• Lithium Battery Backup: Onboard battery provides emergency power to ensure access control readers, door locks, and emergency communication systems remain operational during outages.

Deployment Considerations:

• Verify PoE switch capacity and available power budget before deploying multiple TANGO1B units on the same switch. Most enterprise switches support 90W per port; confirm your switch model supports the required current draw.
• Battery runtime depends on connected load current. During procurement, confirm runtime requirements for your specific devices (typically 4–8 hours for door locks and card readers at full draw).
• Install the TANGO1B in a location with moderate ambient temperature. While lithium batteries tolerate wider temperature ranges than lead-acid, avoid direct sunlight and high-heat environments to maximize battery lifespan.

For integrators deploying access control, surveillance, or emergency communication systems in distributed sites, the TANGO1B delivers reliable backup power in a form factor that fits real-world constraints. Pair it with enterprise-grade PoE switches and standard battery monitoring tools for a robust, maintainable infrastructure.
