Axial PC fan MDA series

The MDA Series features a built-in alarm circuit that the host controller can recognize if the fan speed drops. This is important for noticing quick drops in the cooling capacity of the fan caused by the end of the service life of the fan or by ingress of a foreign object. The MDA Series is available in frame sizes from 2.44 in. (62 mm) up to 5.51 in. (140 mm). Lead wire and connector types are available. Low Speed Alarm Types An alarm is output when the fan speed drops due to the service life of the fan or ingress of foreign objects. This makes it possible to order and replace the fan with a new one before it stops. If multiple cooling fans are being used, it is possible to only replace the cooling fan with decreased cooling capacity. Even if the cooling capacity of the fan decreases, the effect on the equipment can be minimized. Use the MDA Series in the Following Scenarios: When a Spare Fan is Installed An alarm is output when the fan speed drops. As a result no spare fan needs to be installed. Easy-to-Connect Fan Types Available We have a cable with a connector for easy connection in addition to the standard lead wire type. The connector type fan can reduce wiring. Maintenance is also very easy because the fans can be replaced just by disconnecting the connector.
