Features: Adopts switching power supply structure designed, 300KHz frequency of main control chip of the switching power supply, also with overcurrent and over-temperature protections functions, and up to 92% chip efficiency. Small size and lightweight; 5V/6V output can be switched! The electronic components are protected by shielding, and the output line equipped with magnetic-ring, which greatly reduces electromagnetic interference and ensures the normal operation of the receiver. It has the protections function of preventing the polarities of power supply from being reversed, if power supply reversed accidentally, UBEC will not be damaged. With LED working status indicator, it will light up when the output keep normal. Specifications: Material: ABS Length: about 43mm/1.69inch Output Capacity: 5V/3A or 6V/3A (can be switched through jumper-cap); Power Input: 5.5-23V (2-5 series lithium-batteries or 5-15 nickel-metal hydride/nickel-cadmium batteries) Ripple: less than 50mVp-p (@ 2A/12V) Note: Please allow 0-1cm error due to manual measurement. Please allow for slight color difference due to different monitor resolution. Package includes: 1Pc 3A UBEC Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
