CB94B 600W AC Motor Controller | Soft Start & Brake Stop Protection PCB

WHY THIS BOARD

Why choose CB94B

The CB94B AC Motor Control Board is designed for reliable motor startup and protection in AC motor applications.

Supporting AC220V~ / AC240V~ 50Hz power systems and 600W motor applications, CB94B integrates soft start, over current protection, and brake stop functions to reduce startup impact, improve motor safety, and achieve faster stopping performance.

It is suitable for electric tools, small machinery, and OEM equipment requiring reliable motor control and protection.

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.

Stop braking

Active braking brings the motor to a rapid stop when switched off — improves safety and efficiency.

600 W power rating

Optimized for 600 W motor applications — balanced performance for mid-range power tools.
