Radio Power Adaptor

Merlin-3

The Merlin-3™ SBC is an Uninterruptible Power Source (UPS) system for a wide variety of fielded equipment. It can receive input from an extensive range of DC and AC power sources. Its primary function is to export significant power, to run application-specific equipment, laptops and other accessories. The Merlin-3™ SBC also integrates with a BB-XX90 battery contained within the battery box and provides efficient battery charging. In all cases when a battery is available, it serves as a UPS for the attached load. It also manages power for the output when the input is connected and the battery is unavailable.

The hot-swap feature allows battery change-out and maintenance without load interruption. LED indicators display the status of input power, state of charge, battery charging, battery health and output power availability. Peak Power Tracking algorithms efficiently convert power from solar panels to support the load and/or charge the battery for power storage.

The Merlin-3™ SBC latches to battery boxes without any additional tools or modifications. It is compact and rugged, allowing the system to be used in all conditions and environments. The Merlin-3™ SBC does not compromise the environmental integrity of the battery or attached loads.
