Customer Reviews (4.6 / 5 · 5 reviews)

Zoe U. ★★★★★

Wired this into my lathe for variable speed control, and the 10A rating handles my 250W motor without breaking a sweat. The PWM response is smooth even at low RPMs, no stutter or hunting. Direction switching is instant, too.

Miles D. ★★★★★

Finally got my CNC spindle RPM under control with this controller and the 400W rating handles my load without breaking a sweat. The PWM adjustment is incredibly smooth from a crawl to full speed. Exactly what my workshop needed.

Eli M. ★★★★★

The 10-amp rating handles my 400W motor without hiccups, and the PWM control gives smooth speed adjustments down to a crawl. Wired it up in about fifteen minutes, though the terminals are a bit cramped for thicker gauge wire.
