Description Introducing the Hobbywing 25A 3-18S High Voltage UBEC, an external switching-mode DC-DC regulator designed to provide a stable power supply for receivers and other electronic devices in large helicopters and fixed-wing aircraft. This UBEC efficiently steps down voltage from a 3-18S LiPo battery, delivering a continuous current of up to 25A with peak currents reaching 50A. Key Features: High Efficiency: Utilizes a DC-DC regulator chip with a conversion efficiency exceeding 90%, ensuring minimal energy loss. Adjustable Output Voltage: Offers selectable output voltages of 5.2V, 6.0V, 7.4V, and 8.4V to accommodate various servo requirements. Multiple Outputs: Equipped with 8 parallel output channels to enhance current handling capabilities. Comprehensive Protection: Features BEC shoot-through protection, over-current, short-circuit, overheat, and low-voltage cutoff safeguards to ensure reliable operation. Backup Power Support: Includes a backup power input, allowing connected devices to maintain operation if the main power supply is compromised. User-Friendly Design: Comes with an external switch for easy on/off control and an LED indicator to display operational status and backup power connectivity. Robust Construction: Encased in a metal housing that facilitates efficient heat dissipation and reduces electromagnetic interference.
