1. The design of switching power supply control chip using synchronous rectification, the stabilization system of switching power supply mode, has overcurrent and overheat protection functions, and the highest efficiency of the chip is as high as 90%; The output current is large, the continuous output current capability is 6A, and the output current capability is 8A, which fully guarantees the power demand of the equipment 2. The output line is equipped with a filter magnetic ring, which greatly reduces electromagnetic interference and ensures the normal operation of the receiver; It has a wide voltage working range, and can work normally within 8V-25.5V; With LED working status indicator, the indicator will be on when the output is normal; if the LED is not on, please check whether the power input line is well connected 3. Product Usage: UBEC is an external voltage stabilizing device. It works as a switching power supply. It is used for high-current and high-voltage model equipment. It can be used for receivers, gyroscopes, high-voltage steering gears, high-torque steering gears, pan/tilt, video transmission, Power supply for aerial photography system, etc. 4. Product specifications: Output: 5V/6A or 6V/6A or 7.4V/6A (may be switched by jumper cap); Input voltage: 8-25.5V (2-6 lithium battery packs or 6-16 nickel-metal hydride/nickel-cadmium battery packs); Continuous output current: 6A; output current: 8A (duration does not exceed 15 seconds); Ripple: less than 45mVp-p (@2A/12V); Weight: 14g (including wire and magnetic ring). caveat: Although measures have been adopted to reduce electromagnetic interference, a small amount of electromagnetic interference cannot be completely avoided when UBEC in switching mode is working. To the normal operation of the receiver, flight control and other equipment, please keep the distance between the output filter magnetic ring and the main control board as far as possible (the output filter magnetic ring cannot be stacked on the main control board), and make the entire UBEC as far Keep away from the receiver, etc. Instructions: 1. How to use when the brushless ESC (ESC) does not have the built-in BEC function: At this time, there is no need to make any changes to the brushless ESC, as long as the input terminal of UBEC is connected in parallel with the battery pack, and the output terminal is inserted into an idle channel of the receiver. 2. How to use when brushless ESC (ESC) has built-in BEC function: At this time, the BEC output of the brushless ESC must be disconnected, that is, the red connection between the brushless ESC and the receiver must be disconnected, and the rest is the same as in section 5.1. colour: as shown Material: Electronic components Size: 39mm x 21mm x 6mm Package Contents: 1 x External 6A High Voltage UBEC Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
