Professional High-Efficiency UBEC Series

ZTW UBEC 30A HV External Switching BEC 3-18S Dual Input 5.2V-12V Adjustable 60A Peak with 8-Channel Output for UAV, VTOL, Helicopter and Large-Scale Aircraft

30A Continuous / 60A Peak for High-Demand Platforms

The UBEC 30A HV delivers 30A continuous and up to 60A peak output current, powering banks of high-torque digital servos on large-scale helicopters, VTOL tilt-rotors, and industrial UAVs where multiple actuators draw current simultaneously.

3-18S Main Input with 1-2S Backup

The main input accepts 3S to 18S LiPo (9-80V), covering everything from 3S models to high-voltage 18S industrial platforms. A separate 1-2S backup input automatically takes over if the main battery fails, keeping receivers and servos alive for a controlled landing or safe shutdown.

Six Selectable Output Voltages

DIP-switch selectable output at 5.2V, 6V, 7.4V, 8.4V, 9V, or 12V supports standard and high-voltage servos, flight controllers, gimbals, lights, and custom industrial electronics from a single unit.

8-Channel Parallel Outputs

Eight JR-style output connectors can be used independently or in parallel for higher current distribution, eliminating the need for Y-harnesses and providing clean power to receivers, gyros, and up to four servos directly.

Metal Housing with Thermal & EMI Protection

The aluminum-alloy housing dissipates heat rapidly under sustained high loads and shields sensitive electronics from electromagnetic interference — essential for UAVs and VTOL aircraft carrying video and telemetry systems.

Comprehensive Protection Suite

Built-in over-current, over-temperature, low-voltage, output short-circuit, and output anti-backflow protection safeguard both the BEC and connected equipment. An external power switch and tri-color LED (red=main, blue=backup, green=output) provide at-a-glance status.

Designed for Professional & Industrial Use

With dual redundant inputs, 80V max voltage, 60A peak capability, and rugged metal construction, the UBEC 30A HV is equally suited to large-scale RC helicopters, commercial UAVs, VTOL platforms, and ground-based robotic systems demanding reliable servo and electronics power.
