MR9238H24B2-FSR

DC Fans are electric fans that use direct current (DC) electricity instead of alternating current (AC). This type of fan is not powered by the same source as that of AC fans and is not connected to any supply lines. The power source is usually a battery or some other source of direct current such as the power derived from a solar cell. DC Fans are usually more efficient than AC fans, due to their lack of a transformer. This enables a DC fan to consume less power and also allows for a lower cost of fan operation.

The MR9238H24B2-FSR is a DC fan specifically designed for air moving and cooling applications in compact, low-power electronic systems. It features a 9 cm (3.54 inch) diameter, two ball bearings, and an additional fourth wire for fan monitoring. The additional fourth wire enables increased safety monitoring of the fan, allowing it to detect various conditions such as over-voltage, over temperature, and wrong polarity. This fan is ideal for applications such as personal computers, data centers, communications and information technology equipment.

The DC fan MR9238H24B2-FSR is capable of providing reliable cooling in a variety of conditions. It is able to be powered by either a 12-volt or 24-volt DC source. The fan has an operating temperature range of -10°C to 70°C and an operating voltage range of 6.8V to 13.2V. The fan is made of a thermoplastic impeller, a die-cast aluminum frame and endbells, and steel-ball bearings, along with an encapsulated motor-controller for long-term reliability. In terms of air-flow, it can achieve a maximum flow rate of 44.50 CFM, with a noise level of only 34 dBA.

In terms of its working principle, the DC fan MR9238H24B2-FSR operates by spinning its blades, which in turn draw in outside air to create a flow of gas (or air) over a surface. The airflow produced by the fan is then directed over the area needing to be cooled, providing a cooling effect. In addition, the fan can also force air away from areas that need to be kept cool. The fan\'s speed is controlled by a variable-frequency drive (VFD) which can be adjusted to provide different levels of airflows. The VFD is usually powered by a 12, 24, or 48 volt power source.

In conclusion, the DC fan MR9238H24B2-FSR is an efficient and reliable cooling solution for low-power electronic equipment. Its high air-flow and low noise levels, along with its ability to operate in a wide range of temperatures, make it an ideal choice for numerous applications. Its reliable design features a robust motor-controller and steel bearings, and it is capable of operating in either 12 or 24 volt power sources. The fan is also able to provide airflow in a variety of directions, enabling it to effectively cool any area that needs it.
