CB94C 800W AC Motor Controller | Soft Start & Brake Stop Protection PCB

WHY THIS BOARD

Why choose CB94C

The CB94C AC Motor Control Board is designed for high-performance AC motor protection and control applications.

Supporting AC220V~ / AC240V~ 50Hz systems and 800W motor applications, CB94C integrates soft start, over current protection, and brake stop functions to provide smoother startup, improved motor safety, and faster stopping performance.

It is an ideal motor control solution for professional electric tools, machinery, and OEM equipment requiring reliable protection and control.

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.

800 W power rating

Optimized for 800 W motor applications — robust performance for demanding power tools.
