DC-motorstyrning G2 18v15

High-performance motor controller for brushed DC motors with support for multiple control interfaces – USB, serial, I²C, RC, and analog. The SMC G2 18v15 delivers up to 15 A continuous without a heatsink, making it suitable for both prototyping and permanent installations. Includes built-in protection for current, temperature, and voltage. Easily configured via USB with free Windows software. Supplied with header and terminal blocks – soldering required.
