Hi, I got a Power supply (TEN 6101-4030) which should give me 0-50V 0-40A. However, I cannot measure any output (without charge) more than 20V. In any case, as I power the PS with the contrllers connected, Voltage goes down to 0,5V, even without the motors working. As a result the motors dont run at all. I dont underestand what happens here. Can anybody give me some light?

Thanks a lot
