Keep PoE infrastructure online when utility power drops. The Altronix TANGO1B combines power supply and LiFePO4 charging functions in a compact platform built for networked security, access control, and edge deployments that cannot afford downtime. This model is designed for teams that need more than a basic adapter. By supporting LiFePO4 backup charging, it helps maintain stable power delivery to connected PoE equipment while simplifying the power architecture at the rack, cabinet, or enclosure level. That matters when you are protecting cameras, controllers, and other always-on devices across distributed sites. For integrators and infrastructure teams, the value is in the operational margin: fewer single points of failure, cleaner backup power management, and a purpose-built approach to PoE power continuity. When the cost of interruption is measured in lost visibility or delayed response, a dedicated charger and drive power supply earns its place.
