HobbyWing UBEC-10A 2-6S for RC  Electronic Speed Controller ESC with  output voltage  switches  5.0V/6.0V/7.4V/8.4V         The output voltage is programmable by dip switches. 4 Options: 5.0V/6.0V/7.4V/8.4V         1. Introduction The UBEC is an external switching mode DC-DC regulator; it draws the DC voltage from 2-6S Lipo battery, drops it to a voltage level that is suitable for receivers and other electronic devices, and keep providing the stable current output up to 10Amp. As the UBEC has such a powerful output capability, so it is particularly applicable for large helicopters and fixed-wing aircrafts.                  2. Specifications                          2.1 Input Voltage: 6V5.2V (2-6S LiPo)                          2.2 Output Voltage: 5.0V/6.0V/7.4V/8.4V                          2.3 Output Amperage: Continuous Current: 10A, Peak Current: 20A                          2.4 Dimension: 43.1 x 32.3 x 12.5mm (L x W x H)                          2.5 Weight: 36g                          3. Features                          3.1 It adopted the advanced DC-DC regulator chip with conversion efficiency exceeds 90%;                          3.2 4 options for the output voltage, applicable for all kinds of receivers/gyros/servos, etc.                          3.3 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;                          3.4 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;                          3.5 Two cables are connected in parallel at the output end of the UBEC, allow larger current to flow into the receiver.                          3.6 It has one status LED, which lights up when the output voltage is within the normal range;                          3.7 The external switch can turn on/off the UBEC easily;                          3.8 Exquisite aluminum case is helpful for heat dissipation & EMI (Electromagnetic Interference) reduction.
