Item name: BEC Input voltage: 7-26V, 2-6SLiPo (The input voltage must be higher than the set output voltage +0.8V, otherwise the output input voltage is the input voltage minus 0.8V.) Output voltage: 5V, 6.2V, 7.4V, 9V optional. (The default output is 5V, and the other three voltages can be for output through jumper pads.) Adopt MP9744 chip. This is an integrated step-down controller and MOSFET high-efficiency integrated switch step-down chip. The maximum instantaneous output current is 7A, with no heat dissipation, it can continuously output 4A, and with heat dissipation, it can continuously output 5A. Output current (continuous): 1. No heat dissipation (no heat sink, no wind): 5V4A, 6.2V4A, 7.4V4A, 9V3.5A 2. With heat dissipation (with heat sink or wind): 5V5A, 6.2V5A, 7.4V5A, 9V4.5A Output current (instantaneous): 5V7A, 6.2V7A, 7.4V6.5A, 9V6A Immersion Gold: 1u Size: 29x17.8x5.4mm PCB board thickness: 16mm Weight: about 4.6g (including capacitor) Used for RC drone model airplane. Select voltage output through jumper pads (if you need 5V voltage output, please skip this step): Do not short circuit jumper pads, default output 5V. Select other output voltages by short circuiting jumper pads. 1. When selecting the 6.2V solder pad, the actual output voltage is 5.9V; 2. When selecting the 7.4V solder pad, the actual output voltage is 6.9V; 3. When selecting the 9V pad, the actual output voltage is 8.9V. Note:due to different production batches, the printed characters are different, which does not affect the use. Colour:As Shown Material:Metal+Plastic Package Contents: 1 * Module(no connection wire) 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.
