The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

Part-load efficiency is rapidly becoming the most important measure of energy efficiency in chiller units. Around the world, new environmental standards are increasingly based on a combined part-load ...

The SmartFan Inversion fan-speed controller combines an ac/dc power supply and a dc-fan control/alarm. The controller has a supply voltage from 95 to 264 Vac, and supports 24 or 48-Vdc fans rated to 4 ...

This document discusses the operation of the MAX6650 and MAX6651, two fan controllers with linear closed-loop fan speed control. Temperature-based fan control is a necessity in a growing number of ...
