On DEC. 29,2007,Teking issued the “KK70”—the DC motor controller series formally.
To this electric tricycle controller series projected on Apr. 2nd ,2007,we spent R&D funding and energy. Inspected the electric tricycles in Hebei,Zhejiang,Jiangsu etc. Groped the need of the manufactures, distributors and the consumers . learned the advantages and the disadvantages of the controllers in market. Repurchased many tricycles for research. And after all of these effort ,we  developed the high-quality electric controller.
We can conclude :meet the need of the mainstream electric tricycle ,overcame the disadvantage of most controllers. Also, this kind have its own core technology: great power mode. At present , the power of the controllers in market are generally inadequate. ,and this phenomenon will be much  obvious during starting , climbing ,heavy load. Teking’s  controller can detect this situation automatically. And then start the great power mode  in few ms, and output the great power which is 2 times greater than that  before. Overcome the  original state .
Teking’s controller have several special functions : anti-coaster protection.(when breaking failures ,cut the output automatically, this reduced the risk of destroy . )2: automatic cruise feature. 3.set speed manually
Teking’s KK70 series , Including” 24V 36V 48V 60V 72V 84V”，“2kw 1.5kw  1kw  0.8kw 0.5kw ”,can be used in electric leisure cars, classic cars, solar boat, clean cars, four-wheel electric cars etc. and also can be used in the  permanent magnet brush dc motor of the same power and the same voltage.
At present , this  product have the appearance patent  and software copyright patent ,which can protect the uniqueness of the distributor effectively.
Teking’s KK70 must be the mainstream product one day!
