5V 6V RC UBEC 3A Max 5A Lowest Full Shielding Antijamming Switching Regulator 1. Adopting a switching power supply structure design, the main control chip frequency of the switching power supply is 300KHz, and it also has over-current and over-temperature protection functions, and the chip efficiency is as high as 92%; 2. Very small and light in weight; 3. The electronic components are protected by a shield, and the output line is equipped with a magnetic ring, which greatly reduces electromagnetic interference and ensures the normal operation of the receiver. 4. It has the protection function to prevent the reverse polarity of the power supply. If the power supply is accidentally connected reversely, the UBEC will not be damaged. 5. It has LED light-emitting diode working status indicator light, which lights up when the output is normal. 6. Advantages compared with traditional BEC: Compared with BEC using linear voltage regulation, the advantages of BEC using switching power supply are mainly reflected in: when using more than 3 strings (11.1V) batteries, BEC heat generation can be greatly reduced and the battery life can be improved. Overall efficiency. Product specifications: 1. Output capability: 5V3A or 6V3A (can be switched by jumper cap); 2. Power input: 5.5-23V (2-6 lithium battery packs or 5-15 nickel metal hydridenickel cadmium battery packs) 3. Dimensions: 43mm x 17mm x 7mm (length x width x height) 4. Weight: 11g 5. Ripple: less than 50mVp-p (@2A12V)
