Aircraft Model BEC 12S-PRO Reduction Module: This product is a reduction module designed specifically for aircraft models, which can reduce the high input ranges (9V to 55V) to a stable output protections: Equipped with protections function, it can effectively prevent overvoltage damage caused by change, enhancing the safety and stability of the product. Wide input ranges: suitable for input ranges of 9V to 55V, allowing the reduction module to meet power requirements of aircraft modeling equipment. Stable output to steadily reduce the input and output a stable to the aircraft modeling equipment, ensuring the normal operation of the aircraft. Efficient and energy-saving: adopting efficient reduction conversion technology to minimize energy loss and provide longer battery life.<br><br>Wide working input ranges from 9V to 55V, with protections. 3x output option, 5.2V, 8V, or 12V, default to 5.2V. Synchronous switching regulator with a typical efficiency of 88% to 96%. Supports continuous output current of up to 5A and peaked current of 9A. Output rippled 30mV (VIN=50V, output 5.2V @ 5A), 60mV (VIN=50V, output 12V @ 5A) Standby current:5-10mA No reverse input protections Thermal shutdown Output short-circuit tolerance (2 seconds) Overcurrent protections & self recovery Differential 2V (input equal 14V is necessary for a stable 12V output) Pin spacing:3.81 millimeters Color:Blue Material:ABS Size:. 35x24x5.5mm/1.38x0.94x0.21inch<br><br>Package Contents: 1 * Buck Module<br><br>Only the above package content, other products are not included.
