Feature: 1. [7 to 25.5V Input] This UBEC can obtain DC voltage from an input of 7 to 25.5V and provide a stable output current of up to 4A to power devices such as receivers, gyroscopes, and multiple servos. 2. [Efficient Design] Utilizes synchronous rectification switch power control chip with over current and over temperature protections, achieving up to 93% efficiency. 3. [Large Output Current] This UBEC offers large output current of 4A continuous and 6A maximum, ensuring sufficient power supply for devices. 4. [Anti Interference] The output line is equipped with anti interference loop, which greatly reduces electromagnetic interference and ensures the normal operations of the receiver. 5. [Safety Feature] With the function of preventing input polarity reversal, and incorrect input power polarity will not damage the device; Equipped with working status indicator light, which lights up when the output is normal. 6. [Practical Tool] With this device, you can directly obtain the power required by the receiver from the power source without having to equip a separate receiver battery pack.
