Toroidy TS series single-phase standard grade power transformers

Toroidy TS single-phase toroidal power transformers span output ratings from 20 VA up to 2000 VA for Class II electrical devices.

By utilizing continuously wound high-permeability steel ring cores, these units achieve minimal nonload excitation current, diminished core heating and superior operational efficiency under heavy duty industrial loads.

TS power transformers offer high volumetric power density within compact dimensions, reducing the overall weight of equipment chassis compared with conventional laminated EI transformers.

Standard secondary outputs range from 10 V to 50 V, with dual center-tapped secondary options available for symmetric analog circuits, industrial automation and control relays.

Toroidy TSA audio grade and flagship Supreme V2 power transformers

Engineered for high-end audio preamplifiers and power amplifiers, Toroidy TSA and Supreme V2 series deliver silent operation and pristine power delivery.

TSA audio models feature protective black Mylar outer tape, vibration-damping neoprene mounting discs, and solid epoxy resin centers with an integrated through-hole for straightforward M6 bolt mounting.

The premier TSAS Supreme V2 series utilizes laboratory-screened magnetic cores with maximum induction and undergoes full vacuum epoxy impregnation within polished non-magnetic stainless steel enclosures.

Between primary and secondary coils, an integrated SYN-SHIELD pure copper electrostatic screen eliminates high-frequency line noise and electrical interference.

Toroidy TTG series toroidal output transformers for vacuum tube audio

Toroidy TTG audio output transformers introduce the benefits of toroidal core geometry to tube audio equipment.

Through proprietary multi-section interleaved winding methods, design engineers succeeded in minimizing both stray leakage inductance and inter-winding distributed capacitance across the full frequency range.

TTG output transformers support Push-Pull and Single-Ended topologies using KT88, KT120, KT150, 300B and EL34 power tubes.

Precision forty-three percent ultra-linear screen taps optimize the operating points of output tetrodes, delivering extended linear frequency reproduction, minimal phase distortion and articulate acoustic bass performance.
