It is totally not allowed to connect our mainline crawler robot system directly to a generator. The voltage from the generator is not very stable.Hereby,we have to warn our customers to buy a extra regulator equipment for it. Our system's requirement is 110-180V or 200-240V,50-60Hz. If the power supply is over 180v but lower than 200v,it still can't run our equipment or even damage the complete system.
