Feature: 1. Product Usage: UBEC is an external voltage regulator that operates in switch mode, allowing you to directly obtain the power required by the receiver from the power source without the need for a separate receiver battery pack 2. For RC Helicopters: Obtain DC voltage suitable for the working of receiver, servo, and other equipment from an input of 7-25.5V, suitable for large RC electric fixed wing airplanes and electric helicopters using 4S or more battery 3. High Efficiency: Adopt synchronous rectifying switching power supply control chip, with over current and overheat guard function, the highest efficiency of the chip up to 93%; With 6A continuous output current, 8A maximum current 4. Stable and Versatile: The output line is equipped with anti interference loop, which greatly reduces electromagnetic interference and ensures the normal work of the receiver; Has a wide voltage working range and can operate normally within 7-25.5V 5. Secure Design: This voltage regulator module has the function of preventing input polarity reversal, and incorrect input power polarity will not damage the device; Equipped with a working status indicator light, which lights up when the output is normal Specification: Item Type: UBEC Voltage Regulator Module Output: 5.0V 6A, 6.0V 6A, 7.4V 6A (switching over the jumper cap), Maximum Output Current: 8A (not exceeding 15 seconds) Input: 7-25.5V (2-6S LiPo, 6-16 Cell NiMh or NiCd Battery Pack) Ripples: Less than 45mVp-p (at 2A 12V) Size: Approx. 39 x 21 x 6mm / 1.54 x 0.83 x 0.24in. Package List: 1 x Voltage Regulator Module 1 x User Manual
