First,We didn't develop the frequency conversion product more than 2L.
Second,in the product series of 2L,we didn't develop the product with senio function.But we can develop this function for you.It will take around 4 month.
Finally,the 3L product with convention,we don't have many appearances availabe.There are only two models for your choice.
