Toroidal Audio Power Transformer

Model：Customize

Custom toroidal audio power transformers for Hi-Fi, broadcasting, and UPS equipment, meeting UL and CE safety standards with RoHS-compliant materials.

Main Power provides Toroidal Audio Power Transformer.

Toroidal power transformers provides the equipment and electronic circuit with electric power, and provides to step-up and step-down voltage in the fixed supply frequency. Toroidal power transformers can also eliminate the unstable high frequency noise in electric power. By doing this, the equipment can be used steadily and normally.

Single phase isolation Transformers capacity from 30VA to 5KVA, and single phase autotransformer capacity from 50VA to 7.5KVA, like isolating transformer, auto transformer, supply transformer, output transformer, audio transformer, control transformer, step up transformer, step down transformer, three phase transformer, and so on. The design specification conforms to UL and CE safety standards, and the materials, also conform to RoHS standard and UL certification.

It could be extend to EI Core Type Power Transformer and Encapsulated Potting Isolation Transformer.

Main Power Electric's toroidal audio power transformers step voltage up or down at a fixed supply frequency and remove unstable high-frequency noise from the power line. Single-phase isolation models range from 30VA to 5KVA, and single-phase autotransformers run from 50VA to 7.5KVA. Every design meets UL and CE safety standards, and the materials meet RoHS and UL certification requirements. The same toroidal design also extends to EI-core power transformers and encapsulated potting isolation transformers.

High efficiency in transforming electric power
Small volume (compact size), light weight, easy to install
Flexible structure
Low magnetic leakage, low hum/noise, low exciting current, low interference
Totally external insulation

Hi Fi and Hi End Stereo Equipment, DJ Stage Audio Amplifier, Audio / Video Equipment, Broadcasting Equipment, Testing Instrument, UPS, Computer Peripherals, Automatic Control System, Industrial Application, Medical Equipment, Telecommunication Equipment, Lighting Equipment, Wind Energy System, Charger, Security System Equipment, Fire Alarm System, Smoke Ventilation Window System, Linear Actuators Equipment, Overhead Door and Garage Door Equipment, etc.

These transformers use a flexible, compact, and lightweight construction with full external insulation, which keeps efficiency high while cutting magnetic leakage, hum, noise, exciting current, and interference to a minimum. That combination suits both audio work and general power applications. On the audio side: Hi-Fi and Hi-End stereo equipment, DJ stage audio amplifiers, audio/video gear, broadcasting equipment, and testing instruments. On the power side: UPS systems, medical equipment, telecommunication equipment, computer peripherals, automatic control systems, lighting equipment, wind energy systems, chargers, security and fire alarm systems, smoke ventilation window systems, linear actuators, and overhead or garage door equipment.

Q: What capacities and certifications do Main Power's toroidal audio power transformers cover?

A: Single-phase isolation models run from 30VA to 5KVA, and single-phase autotransformers run from 50VA to 7.5KVA. The design meets UL and CE safety standards, and the materials meet RoHS and UL certification requirements.

Q: How do these transformers stay quiet and fit into compact audio gear?

A: The toroidal design removes unstable high-frequency noise so equipment runs steadily, and the compact, lightweight, flexible construction with full external insulation gives high efficiency alongside low magnetic leakage, hum, noise, exciting current, and interference.
