With high capacity transistor and chip microprocessor, smooth and elaborate travel control can be reallised, and duty output is indicated with LED according to the pressing of accelerator.  By-pass contractor is operated by pressing on the accelerator at maximum, and the travel motor can produce maximum output.

By an application of transistor chopper control instead of the conventional magnetic contractor driving method, shockless and smooth loading control as well as engery saving effect can be realised.

Installed on the dash board to adjust the start and acceleration performacne of vehicle.
Travel characteristic is secured in accordance with working conditions, also energy saving effect is improved by it.

Non contract point method accelerator with 16 step control by adopting photo-electric element being semi-permanental control the speed of vehicle softly and accurately.

the status of vehicle, being normal or error, can be indicated on the lED monitor, and appropriate adjustment to be made is shown by conducting of self-diagnosis.  This capability enables vehicle to relaise the utmost safety and maintenance efficiency.
