ZTW UBEC 30A HV 3-18S Switching BEC for UAV & RC Aircraft
ZTW UBEC 30A HV 3-18S Switching BEC
The ZTW UBEC 30A HV is a high-current external switching BEC designed for UAVs, VTOL aircraft, RC airplanes, helicopters, drones, and demanding onboard electronics. It converts the main flight battery voltage into a stable low-voltage output for receivers, servos, flight controllers, gimbals, lighting systems, and auxiliary aircraft equipment.
With 3-18S LiPo input support, adjustable 5.2V / 6.0V / 7.4V / 8.4V / 9V / 12V output, 30A continuous current, and 60A peak current, this UBEC is suitable for large RC models, professional UAV platforms, and low-altitude aircraft power systems that need reliable DC power conversion.
Key Features
- High-current 30A external UBEC / switching BEC for UAV and RC aircraft power systems.
- Wide main input voltage: 3-18S LiPo (9-80V).
- Adjustable output voltage: 5.2V / 6.0V / 7.4V / 8.4V / 9V / 12V for different servo and receiver requirements.
- 30A continuous current and 60A peak current for high-power onboard electronics.
- Metal housing helps heat dissipation and reduces electromagnetic interference.
- 8-channel parallel outputs provide greater current endurance for multi-servo applications.
- External switch for convenient UBEC power control.
- LED indicator shows UBEC working status and backup power supply connection status.
- Built-in protections include over-current protection, over-heat protection, low-voltage protection, output short-circuit protection, and output anti-backflow protection.
