CB66-11 High Power AC Speed Controller

WHY THIS BOARD

Why choose CB66-11

Key features that set this board apart.

Soft start

Gradually ramps up motor power at startup — eliminates jarring impact and extends motor and mechanical life.

Over-current protection

Automatically cuts power when current exceeds safe limits — prevents motor burnout and electrical hazards.

Constant power output

Maintains steady output power as load varies — ensures consistent tool performance under heavy use.

High power — up to 2000 W

Handles heavy-duty motor loads up to 2000 W — built for the most demanding power tool applications.

Dual voltage 120 V / 240 V

Flexible dual-voltage input — compatible with both 120 V and 240 V AC power systems worldwide.
