Power up the entire line of Micro-Make^™ / MicroLux^® Palm-size Miniature Power Tools with our most technologically advanced transformer yet. Delivering an astounding 15 amp maximum output, this latest evolution transformer not only contains special feedback circuitry that automatically boosts the power to the tool when it is under load so that the speed remains constant, it now offers separate controls for speed and torque, allowing the user to dial in the optimum settings for each tool and the work at hand. Never before has such power and precision been placed at your fingertips. Need high speed with low torque for fine detail work? No problem. Want slow speed with high torque for drilling plastic without melting? Easy. Simply set tool speed from 5 to 15VDC with the Voltage control, then dial in torque with the Amps control. Switchable LED display shows the exact setting for each control for ultimate precision. Compact footprint unit (only 5-1/2" wide x 5" deep; 3-1/4" high) includes 2 power output sockets designed specifically for Micro-Make^™ / MicroLux^® Miniature Power Tools, and built-in cooling fan for longer run-time. Plugs into standard 120VAC household outlet.
