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 ...

The ZXBM2000 series of controller ICs offers a complete variable-speed solution for two-phase, dc brushless fan and blower motors up to 100 W. The controllers ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

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 ...

Direct-drive fans waste energy and over-cool gas, reducing efficiency and throughput. Horton’s Gas Thermal Control Clutch ...

I’ve long considered Lutron Caseta the most elegant and user-friendly HomeKit lighting solution. Lutron makes the wall switch smart and works with standard dimmable bulbs; other solutions put the ...
