Description
Chassis Mount Transformer 100-200W – Low Frequency Silicon Steel Audio Isolation Transformer
Furthermore, our Chassis Mount Transformer 100-200W is a low-frequency isolation transformer specially designed for audio equipment and industrial mains power supply. This series covers rated power from 100VA to 200VA, adopting high-permeability silicon steel sheet core to deliver stable signal transmission and power conversion performance.
In addition, this chassis mount audio isolation transformer has two core working functions: it transfers signal voltage and mains power, realizes impedance matching between different circuit modules, and provides reliable isolation to block DC interference signals inside equipment.
We can clearly distinguish low-frequency chassis mount transformers from ferrite high-frequency transformers by core material. Low-frequency types use silicon steel sheets for 50/60Hz mains operation, while high-frequency transformers adopt MnZn ferrite cores working above 20kHz. If you need high-frequency power conversion solutions, you can check our EE55 transformer series for kilowatt-level SMPS applications.

characteristics
Characteristics of Low-Frequency (Line-Frequency) Transformers
- The AC mains input power is directly applied to the primary winding, without the need for high-frequency conversion.
- The magnetic core, typically made of high-permeability silicon steel sheets, operates at 50/60Hz to couple and transfer power efficiently.
- The secondary winding induces a low-frequency voltage, which is then rectified and filtered (if required) to power the load or drive audio circuits.
- The output voltage is determined by the turns ratio of the primary and secondary windings, providing a stable voltage step-up or step-down function.
Additional key features:
- Noise & Interference Isolation: Provides galvanic isolation between circuits, blocking DC components and reducing ground loop noise in audio applications.
- Reliable Power Transfer: Designed for continuous operation at line frequency, ideal for audio equipment and industrial power applications.
- Multiple Output Configurations: Can include multiple secondary windings or taps to provide different voltage levels for various circuit needs.
- Built-In Protection: Often paired with thermal fuses or overcurrent protection to prevent damage under fault conditions.
This chassis mount low-frequency isolation transformer fully complies with official mains audio transformer safety specifications issued by IEC for industrial and audio equipment design.
