What is Hobbywing 10A / 20A UBEC ?

This UBEC is an external switching mode DC-DC regulator; it draws DC voltage from 2-6S LiPo battery, drops it to a voltage level that is suitable for your receivers and other electronic devices, and keeps providing the stable current output of up to 10Amp.
As the UBEC has such a powerful output capability, so it’s particularly applicable for large helicopters and fixed-wing aircraft.

Features of 10A/20A UBEC

It adopted the advanced DC-DC regulator chip with conversion efficiency exceeds 90%.

  • 4 options for the output voltage, applicable for all kinds of receivers/gyros/servos, etc.
  • It owns BEC shoot-through protection, which prevent the input voltage from directly flowing to the output end and causing damages to receivers, servos and other electronic devices.
  • It featured other protections like over-current protection, short-circuit protection (at the output end) and thermal protection make the use more safe and reliable.
  • 2 cables are connected in parallel at the output end of the UBEC, allow larger current to
    flow into the receiver.
  • It has one status LED, which lights up when the UBEC works normally.
  • The external switch can turn on/off the UBEC easily.
  • Exquisite aluminum case is helpful for heat dissipation & EMI (Electromagnetic Interference) reduction.
