AFB0624EH-SP50, DC Fans Fan, 60x25mm, 24VDC, 38.35CFM, 5.76W, 0.24A, 46.5dBA, Ball, 4-Leads, Tach/PWM

Thermal Management\Fans & Blowers\Fans\DC FansPulse Width Modulation FansDelta Electronics Pulse Width Modulation Fans regulate the voltage signal between fully on and fully off, controlling the speed of a fan with a very low power loss in the switching device. When a switch is off, there is practically no current, and when it is on, there is almost no voltage drop across the switch. As a result, power loss is close to zero.
