The original programmable sine controller Kelly KLS 7230ST. The sine signal makes it possible to achieve very precise control of the engine, the absence of noise, the highest possible efficiency and torque, and the possibility of a smooth start from a standstill. It is possible to use a PC or Android to change many settings in a very wide range, namely: Adjust the current supply within a wide range at a certain position of the accelerator handle. Adjust the operating voltage of the accelerator handle, which makes it possible to obtain protection against independent starting from a standstill in case of damage (short circuit of the contacts of the Hall sensor) of the accelerator handle.
