Hobbywing UBEC 25A HV / 50A power regulator, 3S-18S LiPo, 5.2-8.4V

HOBBYWING UBEC 25A HV - a powerful switching DC-DC power regulator designed for stable and reliable power supply of on-board electronics in systems with high input voltage. Supports main power supply from 3S to 18S LiPo (9-80 V) and provides continuous output current up to 25 A with peak load up to 50 A.

The regulator is built on a highly efficient DC-DC conversion circuit with an efficiency of over 90%, which allows you to reduce energy loss and heating during operation. The durable metal case contributes to effective heat dissipation and at the same time helps reduce the impact of electromagnetic interference on other electronics.

The UBEC allows you to choose one of four output voltages - 5.2 V, 6.0 V, 7.4 V or 8.4 V, thanks to which it can be adapted to different types of on-board electronics. Up to 8 parallel output channels are provided, which is especially convenient for systems with several powerful consumers. Built-in LED indicators display the operating status of the device and signal possible malfunctions.

An important feature of the HOBBYWING UBEC 25A HV is support for a backup power source 1S-2S LiPo (3-9 V). In the event of a malfunction of the main power source or the UBEC itself, the connected electronics can receive power directly from the backup battery, which increases the system's fault tolerance.

A complex of electronic protections has been implemented for safe operation: against excess current, short circuit at the output, overheating and excessive input voltage drop. The UBEC's dedicated surge protection prevents high mains voltage from being applied directly to the output and helps protect connected electronics in the event of an internal regulator failure.
