Mini 12 V/DC or 24 V/DC drills can be connected to this power controller. The speed can then be continuously regulated from zero to fast. In this phase-angle control, the torque & thus the power of the motor remain very high even at low speeds. A 12 V/DC or 24 V/DC mains transformer, current 1–3 A (depending on the drill) is required for operation. This dimmer then outputs impulse-controlled DC voltage, which can be used to operate drills &, of course, other DC voltage motors can be operated (for floor models & so on). The power regulator can take loads Max of up to 3 A. A ribbed cooling element of at least~ 50 x 50 x 20 mm is required for operation.
