Filament Transformers are single phase transformers used to drive the low impedance filament of an electron vacuum tube. Step-down transformers are employed in the filament circuit of the X-ray generator to boost the heating current provided to the cathode filaments for thermionic emission.
A transformer is a passive electrical device that uses the electromagnetic induction phenomena to transmit electrical energy from one circuit to another.
Step-down transformers are employed in the filament circuit of the X-ray generator to boost the heating current provided to the cathode filaments for thermionic emission. To heat tube filaments at or close to ground potential, low-voltage filament transformers are used.
One transformer frequently contains the filament windings of many tubes. This occasionally calls for numerous secondary windings. A 5 or 6 secondary transformer requires roughly 50% more size and weight than a single secondary transformer. However, because these multiwinding transformers are smaller than five or six independent units, it is often necessary to build them specifically.
The Global filament transformers market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The “260” line of universal primary, affordable, open frame, plate, and filament transformers now comes in 7 sizes. Its universal main has taps for 50/60 Hz, 100, 120, 220, or 240 VAC. It is intended for use with test equipment, general replacement, low power amps, and preamplifiers. Open frame, economical chassis mount with two holes (.187 dia. = G) in a channel bracket or four holes.
Between the primary and secondary windings, the units have a Faraday shield. The electrostatic shield from Hammond Mfg Co Inc. lessens capacitive coupling from the primary and significantly reduces higher frequency current coupling to the secondaries. at least 5″ length leads.
Osborne creates and manufactures unregulated, high-impedance filament transformers. An electron vacuum tube’s filament is supplied with a specific voltage and current by an unregulated filament transformer. A tungsten tube filament serves as the central component of high impedance filament transformers. By using a regulated voltage source, Osborne frequently works with our clients to extend the life of their vacuum tubes.
