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. 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 88percent to 96percent . 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 Package Contents: 1 * Buck Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
