Delta Electronics / Fans THD PWM DC Axial Fans
Delta THD PWM DC Axial Fans feature low noise, high-performance, high-efficiency, a high strength blade, and advanced motor drive technology. The tubeaxial fans are a ball bearing type with a plastic (UL 94V-0) blade and four wire leads. The fans operate in a current rating range of 0.55A to 8.00A, 10.2VDC to 75VDC voltage range, and a 26.40W to 384.0W power range. The THD fans feature low switching noise of 60dB(A) to 78.5dB(A) and rotate at a rate of 7400RPM to 9500RPM. These fans also offer new bionic blades that optimize fan efficiency and reduces noise up to 6dBA.
Built-in pulse-width modulation (PWM) technology regulates the voltage signal between fully on and fully off, controlling the speed of a fan. The main advantage is that power loss in the switching device is very low. When a switch is off, there is practically no current, and when it is on, there is almost no voltage drop across the switch. Therefore, power loss is close to zero. This thermal technology provides better performance, high reliability, and a cost-effective thermal cooling solution.
