RC Microelectrónica, S.L. - Cooling rack fans, refrigerators and heat sinks

Regarding the model protection IP x 5, NMB-Minebea has increased the performance of its standard products thanks to their versions of DC Brushless fans that are protected against intrusion of dust and water. The level of protection has risen to the IP5x category, according to EN60529. This protection is based on a rubber material Silicon that fully encapsulates the PCB and motor. These added features make DC Brushless fans suitable for applications such as cooling, industrial motor controllers, automotive and, in general, any application that requires the use of these devices in hostile environments. These models are available with IP 54 protection for any format of measure 40 mm (series 1608) and 172 mm (6820 series).

Note that a DC Brushless fan speed can be controlled to optimize cooling, either to reduce the noise and power consumption of the system. There are various methods of speed control for fans DC, being one of the most important control by PWM. This method allows the fan control through the speed control cable. The control is carried out through a rectangular signal of a certain frequency. Time control signal is ON against the time is OFF (duty cycle) is that mark the speed at which the fan.
