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 and 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 and, of course, other DC voltage motors can be operated (for floor models and so on). The power regulator can take loadsMax of up to 3 A. A ribbed cooling element of at least~ 50 x 50 x 20 mm is required for operation.
This current conduction switch automatically switches a second device on or off when a DC device is switched on. For example, the radio automatically switches off when the CB radio in the car is turned on, or the radio amplifier automatically switches on when the CB radio transmits. It can automatically switch off an outdoor caravan light when the interior light is switched on. It can also be used to check whether vehicle lights are working (current conduction test). The module is simply connected in-line with the power supply of the device (6–30 V/DC) and uses a potential-free contact (1 x UM, Max 3 A) to switch other devices on and off. The module responds to currents between~ 1–5 A.
