For controlling a 4-branch stepper motor (bipolar) 3 - 17 V, max. 2 A. A double power cable (split power supply) is needed for the power supply. The motor can either be controlled by hand on a computer keyboard or over a previously written program, which runs automatically. Over an interface splitter (part no.: 19 11 15) up to 4 stepper motors can be concurrently controlled by a single stepper motor interface.
Continuously adjustable speed for low-voltage electric motor. This motor is mainly used with DC power drills, model cars, windshield wiper drives as well as electronic tools. Due to the pulse duration control, which works with an adjustable frequency between 600 Hz and approx. 2 kHz, the power loss is kept minimal even at low speeds. The output current from 0 to 10 A can be continuously adjusted with a trim-pot.
This pulse duration controller offers continuous brightness control of lamps or speed control for small power drills and other DC motors. Setting range from 0 to 100% An adjustable current limiter (only in kit version) protects the circuit from short-circuits or blocks the motor shaft.

This control circuit is suitable for the exact control of DC motors, brightness regulators, small heating resistors and much more. The circuit converts a DC voltage into a row of pulses, whose duration is proportional to the set control voltage. The big advantage is that almost no performance is lost through the control circuit. Protective measures against overload and short-circuits.
