ZTW UBEC 12A G2 External Switching BEC 3-14S 5.0V-8.0V Six-Step Adjustable 18A Peak for RC Helicopter, Airplane, Drone and Servo Power
12A Continuous / 18A Peak for Mid-Size Platforms
The UBEC 12A G2 delivers 12A continuous and up to 18A peak output — bridging the gap between the compact 8A and the heavy-duty 30A, ideal for 500-700 class helicopters, 6S-12S airplanes, and mid-size UAVs running multiple HV digital servos.
3-14S Wide Input Voltage
Accepts 3S to 14S LiPo directly, covering 6S sport helicopters, 12S scale airplanes, and high-voltage FPV platforms in a single regulator — no need for multiple BECs across different battery configurations.
Six Selectable Output Voltages
DIP-switch adjustable output at 5.0V, 5.5V, 6.0V, 6.5V, 7.0V, or 8.0V, matching standard analog servos (5V/6V), mid-voltage digital servos (6.5V/7.0V), and high-voltage 8.0V servo systems with fine granularity between the 8A's four-step and 30A's high-voltage ranges.
High-Efficiency Switching Regulation
Switch-mode topology runs cool and efficient, maintaining stable output voltage even when the main battery sags under full-throttle motor loads — preventing receiver brownouts and servo glitches during aggressive 3D or aerobatic sequences.
Compact Heat-Shrink Package
At 60×34×15mm and 51g, the 12A uses a lightweight heat-shrink enclosure that fits helicopter frame trays and airplane fuselages without the bulk of a metal-cased BEC, while still handling significantly more current than the 8A.
Clean Isolated Power
The external BEC isolates receiver and servo power from motor-generated electrical noise, providing a clean supply for flight controllers, gyros, and telemetry modules — reducing interference in both sport and professional setups.
Versatile Across RC & Industrial Use
Suitable for RC helicopters, fixed-wing aircraft, drones, and boats, as well as robotics, gimbal systems, and small industrial actuators requiring a stable, adjustable 5-8V supply from a 3-14S battery.
