The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Fan noise and power are directly related to the output performance of the fan. The fan speed controller is designed for AC Infinity AXIAL series fans and other muffin AC fans rated 100 to 125V AC to enable speed control. Infineon’s fixed frequency CoolSET™ delivers higher efficiency performance and lower switching frequency at mid and light load condition that is enabled by an integrated frequency reduction operation. A comprehensive array of safety features helps to minimize the number of external components, reduces design in time and improves the reliability of the SMPS. That is all it takes. … AC fans can be controlled from a wall control, pull cord or remote, while DC fans can generally only be controlled by remote (very few exceptions – see below*). Introduction Of PWM. I was able to get about 6v but that was the limit. With new global standards (US DoE and EU COC) higher efficiency will be mandatary in SMPS design and here Infineon's SR families can be used to meet the higher efficiency standards. The 3-wire fan has a tacho signal, which indicates the speed of the fan. Remotes are more likely to be lost, broken, run out of batteries. : 210–211 AC motor. With Infineon’s high performance and wide offering of integrated AC-DC power stages, as well as PWM-PFC controllers, Infineon delivers the formula to supercharge your AC-DC  design. Why complicate something so simple. computex 2019 booth tour antec have some amazing stuff on … [PLUG AND PLAY]: The AC power adapter increases maximum fan speed and enables the fan to be powered through an AC outlet; Just plug it into a socket and start the fan [SPEED ADJUSTABLE]: With the variable speed controller, you can adjust the fan speed easily, optimal it to suitable airflow levels and noise; Maximum speed is 3000 RPM > Products Infineon’s latest generation of CoolSET™ AC-DC integrated power stages in fixed frequency and quasi-resonant switching scheme offers increased robustness and outstanding performance, which is enabled by the integration of the latest 700V and 800V CoolMOS™ P7 superjunction MOSFET family in both DIP-7 and DSO-12 package. I tried to increase the lower end of the controller to 8 volts by increasing the value of R3. After all, it’s just another component to deal with and anything extra adds additional cost to the system. The result with either is AC-in, DC-out. Get to know the basic concepts of passive and two-level active rectification methods. Brushless DC fans tend to be the solution of choice for most electronic enclosures. A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface. 苏ICP备15016286号-1 | 苏公网安备 32021402001016号 | 营业执照, Home By offering a wide variety of highly efficient control ICs we enable our customer to meet new demands like PFC regulations and ultra low standby power requirements in a very cost effective way. The Pros and Cons of AC fans. > AC-DC Power Conversion This statement may be true for most typical applications, but applications that are sensitive to noise and power, this option adds value! Infineon’s PFC controllers support both DCM and CCM with the latter supporting wider VCC operating ranges. AC fans are commonly used because the AC outlets are readily available in our houses. 苏ICP备15016286号-1 | 苏公网安备 32021402001016号 | 营业执照, Home The DC controls typically have 6 speeds since DC voltage is easier to control evenly whereas AC is always 3 speed. This means that, the DC fan must have an AC to DC converter, either externally or included internally in the DC fan to convert AC to DC Voltage to power the DC fan. It fits perfectly for your home appliances, aircon, fans, motor control, cooling compressors and pump systems. DC fans are generally faster to respond to the remote control, have more speed options and have the reverse function on the remote. It is important to note that the controllers for AC and DC types of ceiling fan are entirely different and cannot be used for each other. AC & DC Fan Kits Choosing the optional fan kit with your next enclosure will increase airflow in the cabinet while keeping temperatures at bay inside. With new global standards (US DoE and EU COC) higher efficiency will be mandatary in SMPS design and here Infineon's SR families can be used to meet the higher efficiency standards. AC Infinity, Fan Speed Controller for 100 to 125V AC Axial Muffin Cooling Fans, Single Connector, for DIY Cooling Ventilation Exhaust Projects 4.6 out of 5 stars 470 $13.99 $ 13 . 99 An overview of Infineon's synchronous rectification product offerings. Interest has been growing in integrated circuits for controlling the speed of cooling fans in personal computers and other electronic equipment. DC fans use up to 70% less energy than an AC fan.
