Why excavator bucket adaptorer has a lower output voltage?

　　If the output voltage for excavator bucket adaptorer is too low, then we can solve this problem from the following two different reasons:

　　If there are something wrong with the electric road or the switch electric power has the overloads and short circuit problem, such as the DC transformer device has the short circuit problem or its performance is not very excellent, they all can causes the excavator bucket adaptorer has a lower output voltage. So firstly, users need to cut off all of the loads, which carried on the switch electric road, check if there are some problems had produced on the switch electric road or overloads electric road.

　　But after we had cut off all of the load electric road, but the output voltage for excavator bucket adaptorer had change into the normal range, then we can confirm this excavator bucket adaptorer had suffer the too big loads. But after cut off the loads electric road, the output voltage is still very low, then we can confirm the switch electric road has some problem and need to been repaired.
