The Genesis CUBE is composed of a DC power supply used has been built to safety circuits and has been tested by the Australian Government testing facilities to ensure it complies with both electrical and medical standards. This unit (made to US Patent No: US6555071 specifications) is powered by alternating current (AC), the power supply converts the AC to direct current (DC) with a power output of about 18-24 volts. Fuse protection on both the active and neutral power cables have been added and a thermally operated circuit breaker protects the user. Double bobbin construction gives double insulation between the AC and secondary DC windings. Therefore, the AC power stays on the AC side of the circuitry. There is no direct electrical connection from the main supply to the output.
