At Leeds Transformer, we design and manufacture a comprehensive range of Transformer / Rectifier / Thyristor Controlled Units (TRUs), providing robust and highly efficient DC power solutions tailored to suit a wide array of industrial applications. Our TRUs are expertly engineered to integrate transformers and rectifiers into a cohesive system that seamlessly converts AC power into stable and reliable DC output. Whether the requirement is for precision performance or heavy-duty endurance, our units are designed with versatility and durability in mind.

We offer both air-cooled and liquid-cooled TRU configurations, giving our customers the flexibility to choose the most suitable solution for their specific operating environments and performance requirements. With power ratings ranging from as low as 1 kW to as high as 500 kW, and with service voltages reaching up to 6 kV, our TRUs are capable of supporting a broad spectrum of industrial processes, from light-duty operations to highly demanding electrical applications.

Over the years, we have successfully delivered high-current TRUs for specialised uses, including a 96.25 kW low-voltage, high-current air-cooled transformer equipped with controlled thyristor rectifiers. This particular solution not only illustrates our technical capability but also our commitment to meeting challenging and precise customer specifications. We pride ourselves on our ability to rise to complex engineering demands, delivering bespoke equipment that performs reliably in the most rigorous of conditions.

At Leeds Transformer, we go beyond standard offerings by designing fully customised transformer systems with integrated thyristor control for precise output management, as well as specialised transformers for voltage increase or reduction to suit varied applications. Our TRU’s are engineered with energy efficiency, safety, and long-term reliability in mind. Combining technical expertise with a customer-focused approach, we deliver complete, dependable DC power solutions tailored to each application—backed by precision engineering and a genuine commitment to quality.
