This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
Some voltage-regulator tubes contained small amounts of radionuclides to produce a more reliable ionization. [1] The Corona VR tube is a high-voltage version that is filled with hydrogen at close to atmospheric pressure, and is designed for voltages ranging from 400 V to 30 kV at tens of microamperes.
User manuals and user guides for most non-trivial PC and browser software applications are book-like documents with contents similar to the above list. They may be distributed either in print or electronically. Some documents have a more fluid structure with many internal links. The Google Earth User Guide [4] is an example of this format.
Diagram symbols for pressure reduction and back pressure regulators. The conceptual difference is mainly in which side the feedback is taken from. A pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be ...
Schematic of wiring an induction regulator. Power source is connected to R-S-T rotor terminals. Output voltage is N+1-2-3 terminals. Diagram of electrical phasors for an induction regulator. An induction regulator is an alternating current electrical machine, somewhat similar to an induction motor, which can provide a continuously variable ...
An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC ...
GU-50 was not alone. There were other successors of LS-50 designed by Telefunken. Switzerland's BBC produced P50/1 and later modified version P50/2. They had the same base and pinout as the original LS-50. German Democratic Republic made a P50 that had the same bulb as Soviet ГУ-50. Later RFT made a P50-1 version of their tube.
Modern regulated supplies mostly use a transformer, silicon diode bridge rectifier, reservoir capacitor and voltage regulator IC. There are variations on this theme, such as supplies with multiple voltage lines, variable regulators, power control lines, discrete circuits and so on. Switched mode regulator supplies also include an inductor.
