KAVAN PRO 20SB · BL-ESC 20A · BEC 2,5A

Programmable microprocessor ESC for brushless, sensorless AC motors ("brushless, sensorless") for hobby and sport aircraft models with LiPo/Li-ion/LiFe battery power supply. It uses advanced optimized control technology to significantly improve throttle response and power stage control efficiency. The ESC design considers the high long-term load capacity and durability required in models with a larger number of servos. The ESCs are equipped with a powerful switching BEC with selectable output voltage to provide power to the receiver and servos from the drive battery. A special KAVAN PRO LED programming card, supplied separately, is used for easy ESC setup. DESCRIPTION AND FUNCTIONS OF THE ESC The ESC features a high-performance 32-bit ARM M4 microprocessor with a clock frequency of up to 72 MHz; it is compatible with most brushless motors. Suitable for the vast majority of aircraft brushless motors powered by 2-4S LiPo/Li-ion/LiFe batteries. Special power stabilizer for microprocessor for high interference immunity and reduced risk of loss of control. Optimized control technology significantly improves throttle response and power stage control efficiency and reeduces ESC temperature. Powerful switching BEC with output voltage 5.2 V and load capability of 2,5 A continuous and 4 A peak. The BEC is decoupled from the other regulator circuits, it can maintain proper operation even if the regulator's power board MOSFET transistors burn out. Normal/Soft/Very Soft start-up modes are suitable for normal propeller aircraft and models with EDF. Easy programming and setup using the transmitter or the KAVAN PRO LED programming card. A special programming cable for connecting the ESC to the LED programming card allows the user to program the ESC anytime and anywhere (see the KAVAN PRO LED programming card manual for details). Normal/Proportional/Reversal brake modes (especially reversal mode) can effectively shorten the range after landing. A number of protection functions: start-up protection, thermal protection of the ESC, thermal protection of the capacitors, overload protection, overcurrent protection, abnormal supply voltage protection and control signal loss protection effectively extend the life of the ESC. Calibrate the throttle range to perfectly match the control signal from your RC kit.
