KAVAN R-20B NOZZLE 20A

ESC DESCRIPTION AND FUNCTIONS

Extremely low internal resistance thanks to a new generation of power MOSFET transistors.

Suitable for the vast majority of aircraft brushless motors powered by LiPo/Li-ion 2-3S or NiCd/NiMH 5-9 cell batteries.

For powering from NiCd, NiMH, LiPo, Li-ion batteries.

5.0 V linear BEC with charging capacity up to 2 A.

Adjustable time delay for optimal adaptation to the motor.

Adjustable voltage protection - disconnects the motor in case of a drop in supply voltage.

Safe power-up (prevents the motor from starting when powered up).

Overload protection (when temperature reaches 110°C, ESC limits power).

Automatic throttle cut-off if control signal is lost.

Linear throttle control.

Easy programming and adjustment with the transmitter or the KAVAN R LED programming card.

Calibrate the throttle range to perfectly match the control signal from your TX.

PROGRAMMABLE FUNCTIONS

Programmable brake (Off - On).

Optional battery type (Li-poly or NiCd/NiMH).

Adjustable motor cut-off type in case of supply voltage drop (power reduction or immediate disconnection).

Adjustable cut-off voltage for motor disconnection - voltage protection against battery over-discharge (lithium batteries: 2.85 V/cell, 3.15 V/cell, 3.3 V/cell.NiXX batteries: 0%/50%/65% of the initial voltage value).

Soft start adjustable in three steps for motors with gearbox and helicopters: Normal (300 ms) / Soft (1.5 s) / Super Soft (3 s).

ESC PROTECTION FUNCTIONS

Start-up protection: If the engine does not start within 2 seconds after the throttle is applied, the ESC disconnects the engine.

Thermal protection: If the ESC temperature exceeds 110°C, the ESC limits the output power.

Loss of signal protection: The ESC will limit power if the signal is absent for 1 s; an absence of signal for more than 2 s will result in complete disconnection of the motor.

Tip: When the controller is switched on for the first time, the throttle range must first be calibrated according to the instructions. Only then can the ESC be used and other parameters set using the transmitter or the KAVAN R LED programming card.
