The 8A-UBEC (2S to 5S) is a switch mode DC/DC regulator, it outputs a consistent safe voltage for the receiver, gyro and servos.
It is very suitable for big size RC helicopter and airplanes when the built-in BEC of the speed controller only has limited output capability.

Specification

• Output Voltage: 5.2V@8A or 6V@8A (Selectable by a switch) 
• Continuous output current: 8 Amps
• Input: 5.5V-18.5V (2-5S Lipo or 5-18 cells NiMH /NiCd) 
• Size: 62mmX27X5mmX10mm (LXWXH)
• Weight: 24g

Features

• Advanced switch mode DC-DC regulator has powerful output. 
• High efficiency up to 90%.
• The metal shield and the filter significantly reduce the electromagnetic interference.
• The working status is shown by an LED, it lights when the UBEC works normally.
• With a step-down voltage regulator wire as accessory.

(It changes the output from 6.0V to 5.3V for some special equipments cannot work with 6V).
