BUB0705H-BU27 Delta 5V DC Blower Fan

Description

The Delta BUB0705H-BU27 is a high-performance DC Blower Fan with measuring dimensions of approximately 75 x 75 x 30 mm. It operates on a nominal voltage of 5VDC and draws 0.50 A of current, resulting in 2.5 W of power consumption. The fan features a 4-Wire termination, indicating support for PWM (Pulse Width Modulation) control and Tachometer (speed monitoring) feedback. This fan is primarily designed for high-efficiency thermal management in digital projectors, where it provides the high static pressure required to cool sensitive components in a confined space.
