Features: For brushless motors, this high voltages driver board supports 110/220V input with built in overload, over temperature, over/under voltages protections, ensuring safe operations under 1A output current. Featuring industrial components and clear terminals markings, the control board delivers stable performances in harsh environments while enabling quick installation through its plug and play wiring design. for automation engineers, appliance manufacturers, and HVAC technicians requiring robust motor control solution with multiple protections safety features. Optimized for industrial equipment, highly power fan, and automated systems where voltages fluctuations and thermal stress demand fails safe motor driver performances. Its PCB optimized layout integrates four tiers protections mechanisms (thermal cutoff, current limiter, voltages monitor) to extend motor lifespans and prevent electrical hazards in 110V/220V applications.
