The stepper drive PSR5042 is a high performance microstepping driver based on pure-sinusoidal current control technology. Owing to the advanced technology, it could output smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets.

The stepper drive PSR5042 is suitable for a wide range of stepping motors, from NEMA size 17 to 24. It can be used in various kinds of machines, such as X-Y tables, engraving machines, labeling machines, laser cutters, pick-place devices, and so on. Particularly adapt to the applications desired with low noise, low heating, high speed and high precision.
