Tector Toroidal Transformers
Efficiency and reliability at the service of your applications.
Key Features
Tector's toroidal transformers represent an advanced solution for those seeking high performance, energy efficiency, and compact design.
Thanks to their toroidal core design, these transformers offer numerous advantages over traditional transformers, including lower no-load losses, reduced electromagnetic fields, and near-silent operation.
Our technical department designs and manufactures custom toroidal transformers suitable for a wide range of applications: from electronics and lighting systems to medical devices, Hi-Fi audio systems, and custom solutions for automation and smart home technologies.
Each transformer can be tailored to customer specifications, with flexible options for:
- Power ratings (from 10VA to 10kVA)
- Primary and secondary voltages
- Connections (wires, faston, terminal blocks)
-
Insulation classes and thermal protection

MAXIMUM PERFORMANCE IN A COMPACT FORMAT:
ADVANTAGES OF TOROIDAL TRANSFORMERS
High Energy Efficiency
The core shape significantly reduces magnetic losses, ensuring excellent energy efficiency.
Low Noise Operation
The toroidal structure minimizes vibrations and humming typical of laminated transformers.
Minimal Magnetic Leakage
The design reduces magnetic flux loss, improving efficiency and enabling smooth energy transfer between windings.

Fully Customizable on Request
Each transformer can be configured for power rating, voltages, pin-out, shielding, protection level, and mounting type.
Compliance with CE and RoHS Standards
All products are CE and RoHS compliant and undergo strict quality controls.
Compact Design and Easy Installation
Symmetrical and compact design, easy to mount even in tight spaces or on electronic panels.
Available Types of Toroidal Transformers
Tector offers a full range of toroidal transformers to meet any application need — from standard production to protected, accessorized custom solutions. Each model is designed according to European standards and built with certified materials.

1. Standard (Open Frame)
Toroidal transformers without encapsulation, ideal for integration in systems where no additional mechanical protection is required. Mounted via central screw or bracket. Ideal for: installation inside protected enclosures.
Main features:
- Minimal footprint
- Excellent natural cooling
- Easy to integrate into OEM projects

2. Boxed version
Mounted inside a plastic or metal enclosure (box), designed to provide greater protection from dust, impacts, or accidental contact. Supplied with mounting holes and ready for quick wiring.
Ideal for:
- Electrical panels
- Industrial installations
- Architectural lighting systems

3. Encapsulated (Resin-Filled)
Encapsulated resin-filled transformers offer excellent protection against moisture, mechanical vibrations, and weather conditions. Essential in critical or outdoor environments.
Advantages:
- IP65/IP67 protection class (on request)
- High thermal and mechanical resistance
- Ideal for dusty or humid environments

4. Enclosed units
Housed in closed plastic or metal cases with protected connections — perfect for systems requiring complete electrical and mechanical protection.
Customization options:
- Colours
- Technical labelling
- Quick-connect terminals

5. Available accessories
To complete the offer and simplify integration, we provide a range of compatible accessories:
- Central or side mounting brackets
- Thermal protection (PTC, thermal fuses)
- Preassembled cables or with connector options
- Shielding
- Custom labels with client logo
- Anti-corrosion treatments and tropicalization
