Very good product at first check. To my nice surprise it come with 2 potentiometers, one multiturn and one single turn. So you have all you need to operate it as soon as you receive it. Only one point to take care of: Voltage selection. The apparatus come with an internal switch to select operation for 240Vac or 110Vac. There is no information on the circuit board, the only reference is on the stick applied outside on the protection carter. To change the position of the switch you have to remove the carter and break another stick on the side probably breaking also the warranty of the power supply. I suggest to open it anyway and check the position, because operating it with the wrong selection could damage the device, and in that case you have to argue anyway with the supplier for a very stupid reason because: - If you open the carter the warranty is void - If you don't and operate it at wrong voltage they can argue that the stick outside advise to check for proper voltage :-)
