The stepper drive PSR8078AC is a high performance microstepping driver based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets.

The stepper drive PSR8078AC is suitable for a wide range of stepping motors from NEMA 34 to NEMA 42, which is widely used in various kinds of machines, such as CNC routers, cutting machines, packing devices, pick-place devices, and so on. Particularly suitable for the applications require low noise, low heating and high speed performance.
