2. Computer fan control - Wikipedia

   en.wikipedia.org/wiki/Computer_fan_control

   A fan controller with LEDs indicating fan status and potentiometers and switches to control fan speeds Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case.

3. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

4. Integrated circuit - Wikipedia

   A microscope image of an integrated circuit die used to control LCDs.The pinouts are the dark circles surrounding the integrated circuit.. An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections.

5. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   A capacitor start motor is a split-phase induction motor with a starting motor capacitor inserted in series with the startup winding, creating an LC circuit which produces a greater phase shift (and so, a much greater starting torque) than both split-phase and shaded pole motors. This motor has a centrifugal switch which disconnects the ...

6. 1-Wire - Wikipedia

   en.wikipedia.org/wiki/1-Wire

   1-Wire is a wired half-duplex serial bus designed by Dallas Semiconductor that provides low-speed (16.3 kbit/s [1]) data communication and supply voltage over a single conductor. [ 2 ] 1-Wire is similar in concept to I 2 C , but with lower data rates and longer range.

8. Isolated-phase bus - Wikipedia

   en.wikipedia.org/wiki/Isolated-phase_bus

   Accessories such as instrument transformers, surge arresters, and capacitors are also made in compatible housings. Due to the expense of its construction and the energy loss, isolated-phase bus is usually used in short segments; a large underground powerhouse may have isolated-phase bus up to about 250 metres or so to connect generators to ...

9. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   DC brushless ducted fan. The two coils on the printed circuit board interact with six round permanent magnets in the fan assembly. A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply.
