Switched mode power supply
A switched mode power supply (switching mode power supply, switch mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting ...LM338 Adjustable Power Supply 5A Elec Circuit
PINS of LM338K To 03 and LM338T TO 220. 1.2 30V, 5A Variable power supply using LM338. We may have the many ways such as: to be modified the LM317 Variable Regulator 0 30V 1A by adding the power transistor MJ2955 in circuit following Adjustable Voltage and current regulator IC power supply or will build the Variable dc regulator 0 30V 5A circuit to be well as well, But these methods.Power supply unit (computer)
A power supply unit (or PSU) converts mains AC to low voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched mode power supplies.Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.. Most modern desktop personal computer power supplies conform to the ATX ...High Current 12V 13.8V at 30A,25A,20A,15A Power Supply
This is 12V high current power supply circuit. A CAR Radio transmitters to use in the home, need a ham radio power supply DC 12V or high current 13.8V power supply with enough power out of 5A,10A,15A,20A,25A, and 30A as you need.0 30 Vdc Stabilized Power Supply with Current Control 0 ...
Hi Mohammed, I have been using this excellent power supply that I constructed since 1982. more than 30 years! It works well. You need to be an experienced electronic constructor for this circuit due to the polarities of diodes and zener diodes, transistors etc.Chapter 5 Power Supply Wiring, Power Consumption ...
H5 1 Chapter 5 Power Supply Wiring, Power Consumption Calculation, and Power Sequence Requirements FBS PLC internally has three kinds of circuit: a 5VDC logic circuit, a 24VDC driver circuit (driver output devices, for example: relay, transistor, and etc), and a 24VDC input circuit.Single Chip VHF RF Preamp Circuit Diagram
Single Chip VHF RF Preamp Here is a high performance RF amplifier for the entire VHF broadcast and PMR band (100 175 MHz) which can be successfully built without any special test equipment.Metal Detector Circuit with Diagram and Schematic
A simple metal detector circuit diagram and schematic using a single transistor and a radio. This metal detector sensor project is easy to make and is an application of Colpitts oscillator.Repairing a Soundcraft Spirit E6 Mixer Switching Power Supply
A few weeks ago, John mentioned to me that one of the audio mixers in the art and technology Internet radio station lab had stopped powering on. I said I’d have a look at the power supply and see if I could fix it, and he sent it with me. Turns out we both got a little more than we bargained for — I in terms of effort required and he in terms of time without the mixer.Sound Allan Gartner
This is only the beginning for this section. If you didn't think so much could be written about speakers for HO, check back when a 4 amp polyphonic sound module becomes available for G — real hi fi speakers in real speaker enclosures — with wheels, of course!
