If you're looking for mains transformers, feel free to check our offer. Transformers designed, produced and deliveried directly form top Polish manufacturer. We guarantee best prices and high-quality products.

What kind of transformers do we have in offer? Here's a brief overview:

• Single-phase transformers
• Three-phase transformers
• Transformer accessories

What exactly are transformers used for? They are devices that adjust the voltage in a single or three-phase network to the voltage needed by the receivers. Transformers are magnetic circuits that contain output windings that are not galvanically connected to the mains.

In the Toroidy.pl online store, you'll find a wide selection of single-phase and three-phase transformers. Feel free to check our offer and if you will have any questions or concerns, please contact us. We'll be happy to help you choose the right solution that meets your needs.

Mains Transformer Classes

The mains transformers available in our online store are available in standard (industrial) class, but also in AUDIO and SUPREME classes. What does this mean? In short, it guarantees even better quality and workmanship than industrial-grade transformers. All transformers meeting AUDIO and SUPREME class requirements are insulated with Mylar tape. Additionally, they're filled with epoxy resin and has a mounting hole for an M6/M8 screw, eliminating the need for mounting brackets. A special neoprene rubber pad mounted on the bottom of the transformer also effectively eliminates vibration.

By choosing our AUDIO or SUPREME class transformers, you can be assured of the highest quality. We only use components that have passed laboratory measurements. Core and windings are additionally impregnated. Electrical shields made of copper tape are placed between the windings, making them safe for use in any audio electronics system, even the most expensive.

SUPREME class devices, including single-phase transformers with additional shielding and encased in stainless steel housings, provide a unique design. The SUPREME class offers uncompromising quality for years to come.

Single-phase and Three-phase Transformers

The role of a transformer is to transfer electrical energy between the primary and secondary circuits, maintaining work frequency. Our offer includes a wide selection of single-phase and three-phase transformers. We offer transformers with various power ratings and output voltages. Below, You can find typical range of products you can find in our store:

• Power - 5VA - 20,000VA
• Secondary voltages: 0.1V to 1.5kV
• Secondary currents: 10mA to 500A

These are just sample parameters. We offer several hundred mains transformers of various types, including custom-made ones. Just use our search engine, simply enter your desired parameters and in just a few seconds you'll see the mains transformers that meet your needs.

Transformer Accessories

We also offer a wide selection of accessories for mains transformers. In our store, you'll find:

• Transformer mountings with neoprene pads (diameters: 50-110 mm)
• DC Blocker devices - to prevent DC mains component
• Soft start systems - inrush current limiters

What types of mountings can you find in our offer? These products are suitable for transformers from 20 VA to over 15,000 VA. Each mount is available as a set with a metal clamp and neoprene rubber washers. It's also possible to encapsulate the transformer in resin.

What are DC Blockers and what are they used for? They are accessories that eliminate DC voltage from the mains, known as DC components. For example, if a transformer is operated near a switching power supply (e.g., a computer or even a washing machine), there's a risk of interference such as humming, an increase in the transformer's temperature, or even distortion in the output voltage quality. This significantly increases current demand, but also the sound quality of audio devices powered by the transformer. We particularly recommend them for tube and solid state amplifiers.

How do soft-start systems work? Their role is to limit high inrush currents at the transformers start. The soft-start systems you can purchase in our store have screw terminals, which facilitate installation even on thick-gauge cables. For even easier installation, we've included diagrams on the housing illustrating how to connect the system to the circuit.
