Specification: Output Voltage: Optional 1: 7.4V/8.4V/9.0V/12V Optional 2: 5V/5.5V/6V/7V/9V Output Current: 0-20 amps Input: 6V - 50.4V (2-12S lithium battery) Quiescent current: 60, 200 Size: 62mm*26mm*21MM (length*width*height) Weight: 30g Features: 1. Adopting the world's most advanced switching power supply main control chip design, with ultra-low impedance high-power FET, with over-current protection function; 2. Small size, light weight, maximum output current of 20A, and extremely strong load capacity. It is the first domestic UBEC with high current output; 3. Using high-power brand components, product performance is stable and excellent; 4. Output voltage can be selected by short-circuit plug (jumper); 5. The dual-wire output is equipped with a professional filter magnetic ring, which greatly reduces electromagnetic interference and wire internal resistance, and ensures the normal operation of the load; 6. Wide voltage working range, which can work normally within 6V-50.4V; 7. Stable operating frequency: 100% duty cycle (Duty Cycle) 8 .Fully enclosed inductors are used to greatly reduce electromagnetic interference. Package Included: 1 x 20A BEC Special Note: In order to better maximize product performance, when using a short-circuit plug (jumper) to switch the output voltage, please do so with the input voltage disconnected to avoid unnecessary trouble. Although various measures have been taken to reduce electromagnetic interference, jdhmbd SBEC in switching regulator mode still cannot completely avoid a small amount of electromagnetic interference when working. In order to ensure the normal operation of the receiver, please keep the distance between the output filter magnetic ring and the main control board as far as possible when using the jdhmbd SBEC (the output filter magnetic ring cannot be stacked on the main control board), and at the same time keep the entire Switch BEC as far away as possible receiver.
