Abstract:
A corded/cordless system for power tools comprising:a low-voltage DC power tool operable in a preselected voltage range, said power tool having an exterior, an interior, a pre-defined interface for mechanically and electrically mating with a power supply module, and a double-insulated case to prevent the conduction of electrical charge from the interior to the exterior of the power tool; and a corded non-isolated power supply module mechanically and electrically configured to connect to a source of relatively high voltage electric power and to mate with the low-voltage DC power tool, said corded non-isolated power supply module being adapted to convert said relatively high voltage line power from the source of electric power to a DC voltage in the preselected voltage range suitable for powering the low-voltage DC power tool.
