Custom OEM Design
Conexa Tech Solutions offers OEM custom and modification services based on proven designs and methods to efficiently move from concept to production. Our capabilities cover everything from low power to high power applications and all common power supply formats to meet a wide range of applications and specific requirements.
Design challenges solved with
tailored solutions
When you need to start from a blank sheet there are always so many questions that need to be answered before committing to the design phase. Mostly it’s about getting the requirement down on paper and ensuring that the i’s are dotted and the t’s are crossed but outside of this there are other challenges that need to be met. These challenges are the requirements that don’t necessarily form part of the specification including factors around commercial requirements, sustainability, repairability, corporate and social responsibility etc. Our tried and tested requirement capturing procedure asks all of the questions so that full customer requirements are captured and agreed prior to project commencement. Our approach is one of consultation and partnership to ensure full understanding of the customers needs.
Our design philosophy is based on the pursuit of technological innovation and excellence. The result is the use of cutting-edge technology for custom solutions that exceed all customers’ expectations. We have multiple design and manufacturing locations including sites in China, Taiwan, Europe, Mexico, India and others. The diversity of factory locations also allows us to select a manufacturing site to assist the customer meet their commercial needs with various terms available depending on customer requirements. We can deliver anywhere in the world through our established logistics partners.
We specialise in high volume manufacturing in ISO certified factories with optimised efficiency and environmentally compatible practices. Many of our production facilities are vertically integrated, manufacturing their own PCB’s, metalwork/plastic cases, cables and wound components. The result is more control, lower costs and a drastically reduced carbon footprint.
In addition to a complete custom design service, we offer an extensive range of reference power supply designs, allowing for a streamlined development process and a faster time to market.

Our Methodology

When ‘off the shelf’ just wont do!
As a company we pride ourselves on having a comprehensive range of standard power supply products which enable most common applications to be provided for. However, despite this extensive range of standard products there are often unique or specific requirements which require a more tailored solution. This may be due to specification, shape/size, environmental requirements, commercial needs, technology or other factors.
In projects where a special solution is required, we offer a Custom OEM and modification service for all general switched mode power supply formats.
To ensure you get the solution you need for any challenge, our bespoke services allow full control over any design and customisations requirements to get that ‘tailored’ fit. Simple to complex solutions are delivered with insight and consideration from engineering experts.
