B, If he CL function is used this restarting inrush current is about the same as the normal running current. Reverse Polarity Protection No damage if the positive and negative leads are reversed under maximum operation voltage conditions. Over Voltage Protection The circuit will be shut down automaticlly when input voltage over threshold. And re-started when Voltage down to threshold below. Soft Start In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.

As the switching of the current is technically known as 'commutating', brushless motors are also called 'electronically commutated' motors. EC motors provide the advantages of brushed DC motors in terms of the ability to have variable speed control, but without the drawbacks of brushes.Q: What are the advantages of EC motors?EC motors are very high efficiency electric motors (80%) and maintain a high efficiency level at part speed. This means that in most cases they use less than one third to half of the electricity used by                    traditional induction motors, which in turn translates into lower operating costs and short payback periods. As EC motors have a higher efficiency this ensures that the motors run cooler in application which ensures a longer life for the motor.In terms of speed control and features, because the motor's operation is controlled by software, EC motors allow customers to optimize and integrate the motor, fan and controller with the application, and to include features like data communications, constant volume control, variable speed.Features & AdvantagesQ: What about cost?The initial outlay for an EC motor is more expensive than the traditional induction / shaded pole motors and this is mainly d
