Car Speed Super

The Car Speed Super ESC from German brand CS Electronic was one of the earliest European electronic speedcontrols. Used as prototype long before, this ESC was released for sale in 1979. Housed in an aluminium case this ESC was using one powertransistor for throttle and a double contact relay for switching between forward and full proportional reverse. This way there was no dynamic brake but active braking through reverse function, most early speedcontrols were designed this way.
