For over 33 years, Electronetics has specialized in providing custom transformer solutions for a wide variety of medical, aerospace, audio, and industrial applications. Electronetics offers a wide variety of line frequency power transformers for 50 Hz, 60 Hz and 400 Hz applications for the avionics to high frequency topologies for aerospace and medical industries, to name a few. Our capabilities include:
Ferro Constant Voltage Transformers: Electronetics has extensive experience designing and building CVT transformers for a variety of applications and regulation profiles as tight as ±3% over wide line and load variations. These highly specialized transformers are designed to enhance and control characteristics that are normally minimized. CVTs require highly controlled leakage inductance (the inductance that prevents any primary voltage from transferring to the secondary) in order to isolate the secondary from the primary. The leakage inductance is electrically connected to a capacitor that forms a resonant tank circuit causing the secondary portion of the magnetic core to saturate. Saturation, something to be avoided in other transformer designs, is exploited to force a maximum limit on the secondary voltage. Line - Line Isolation Transformer: This transformer is typically either 60 Hz or 50 Hz running from a wall socket or from commercial AC. Isolation is commonly listed as a voltage rating for shock safety. Line - Line Autotransformer: Very similar to the line - line isolation transformer but without electrical isolation between the primary and secondary. Frequently used to slightly step-up or step-down voltage to allow for use of smaller core and coil (e.g. stepping up from 208 Volts to 240 Volts or stepping down from 240 Volts to 220 Volts). |

Audio Isolation Transformer: These transformers are often used to distribute an audio amplifier's output to multiple speakers.
Custom High Frequency Magnetics - Transformers & Inductors
Electronetics has extensive experience designing and building custom high frequency magnetic components in virtually every shape, size, frequency and power level.
