DC Rectifier Units
Rectifier Power Transformers
We manufacture air and oiled cooled transformer rectifier units that transform and convert an AC current derived from a single or three phase mains supply to a higher or lower DC Voltage.
This also provides a power supply solution for equipment designed to operate from a DC Power Supply.
Examples are from a few volts at 7000A to inject a current into a railway conduction rail system for testing purposes, up to 5kV at a few amps for running and testing high voltage motors.
We also provide power supply units for the logistics industry and power supply solutions for the motor home and caravan sectors.
Our DC rectifiers are specifically developed to provide a power supply solution for a wide and varied range of applications, such as:
Industrial Automation Automotive Rail Military Marine
Trailer Transformer / Tail Lift Transformer
Electro-Wind specialises in DC rectifiers specifically for use in the logistics industry.
Our AC-to-DC Power Supply Units (PSUs) are specifically engineered for use in distribution and fulfilment centres, delivering a reliable and consistent DC power supply for articulated trailers equipped with tail lifts and full lifting decks.
Developed in collaboration with industry operators, our 300A DC Power Supply provides an efficient and environmentally responsible solution for powering trailers when a tractor unit or shunter is unavailable. By supplying continuous DC power directly to the trailer, it eliminates the need for battery pack recharging, reduces downtime, and improves operational efficiency.
Designed primarily for loading bays, the units can also be manufactured for use in harsher indoor or outdoor environments, helping to create a cleaner, quieter, and safer working environment.
Our Tail Lift Power Supply Units are held in stock and available for immediate delivery, ensuring minimal disruption to your operations.
In addition to our standard product range, we also design and manufacture bespoke AC-to-DC Power Supply Units tailored to your specific operational requirements, providing a solution that meets the exact needs of your application.

Power Supply Unit Assessment & Life Extension Service
Extending Asset Life Through Proactive Maintenance
As part of your Annual Maintenance Programme, we can offer a dedicated Power Supply Unit (PSU) Assessment Service designed to maximise the reliability and lifespan of your critical equipment.
Key Benefits
Reduced downtime through planned maintenance rather than emergency repairs.
Minimised operational disruption by identifying issues before they result in equipment failure.
Lower maintenance costs by repairing or refurbishing serviceable power supplies instead of replacing complete units.
Extended service life of capital assets, maximising the return on existing equipment investments.
Improved system reliability through regular health checks and preventative maintenance.
Sustainable asset management by reducing waste and extending the usable life of electronic equipment.
Our Process
Inspect and assess the condition of the power supply unit at our factory
Test key electrical and mechanical components.
Identify worn or ageing parts that may affect reliability.
Provide a detailed report with recommendations for refurbishment, repair, or replacement.
Complete refurbishment or repairs where appropriate and return the unit to service with confidence.
A Smarter Maintenance Strategy
By incorporating PSU condition assessments into your Annual Maintenance Programme, organisations can move from a reactive maintenance model to a proactive asset management strategy. This not only improves equipment availability but also extends the useful life of valuable capital assets, helping to reduce whole-life ownership costs while maintaining operational continuity.
The units are supplied to your individual requirements with control gear where needed.
Mobile options are available on lockable castor wheels or you can choose from fixed installation units which can be wall or floor mounted.
We have fulfilled many contracts for companies such as:
Marks and Spencer, Argos, T.J.Morris, WHSmith and Next
