12 months ago PSU invested more than £500,000 in additional surface mount and conventional assembly machinery to supplement introduction of lean manufacture, the investment in machinery and the introduction of lean enabling the UK plant to manufacture volume competitively in the UK, all this effort has now come to fruition with record volume output from the UK factory.

The next 6 months will see 5 major new product releases all for manufacture in the UK, look out for further details to follow.

May 2014


PSU Designs has invested heavily in machinery and automation, 2 additional Quadra surface mount assembly machines bringing the total number of these machines to 6 have been installed, a new universal RAD 8 high speed radial assembly machine has been installed as the manufacturing plant continues to grow.
New development orders will see growth of around 30,000 additional manufactured power supplies per year over the next 12 months.

July 2012

Continued growth and record sales

PSU Designs is pleased to report the continuation of growth with sales turn over increase of 14% over the previous 12 months giving record sales for the 4th consecutive year.

The strength and growth of the companies sales and marketing division allied to its engineering resource and technology continues to attract new customers and new business opportunities.

The UK head quarters and manufacturing site has seen a marked up lift in both technical and sales personnel with clearly defined goals for growing both offshore high volume product and low to medium volume more complex UK manufactured product. This has allowed the company to expand evenly across all its operations keeping the right balance in terms of being able to satisfy the needs of all its customers and all its new enquiries no matter how complex or how simple or how high or how low the volumes.

PSU see being able to satisfy all of its customers needs as a key to maintaining their excellent customer relationships, knowing their customers have a partner who will look after their high volumes but who will also be there for the low volume specials.

New Product releases

During the last 12 months the company has released 30 new products, all of them custom designs into a wide variety of markets and industries.


In keeping with the expansion of the companies cutting edge technical capabilities more than half of the new products released have sophisticated micro processor controls bringing a whole host of additional features and house keeping to the power supply’s which in turn gives PSU Designs customers added technology and improved marketing prospects for their own product.

Critical to this advanced technology is the company’s in house software capability which allied to the many analogue engineers gives a unique capability still with fast turnaround of new designs.


PSU continues to be strong in growth markets such a technology lighting, industrial control and many products associated with buildings, refurbishments and infrastructure. Many of the new growth areas require a deep understanding of relevant legislation and the knowhow to meet the legislation and in a timely manner.

Proving and reliability

In keeping with the expansion of the design and technology sode of the business a new department is being created both centralising and adding to the vast amount test and proving equipment the company has at its disposal. Additional ovens, soak chambers, microprocessor controlled active soak test bays and other features are all being added to the enhanced reliability division.

The new features will enable the company to soak test new designs with a programmed variable load profile simulating real use rather than at fixed loads. This forces the power supply to encounter far more transients and deviations into max duty-cycles and other limits of operation that remain tested only during design as a rule but that PSU will be able to prove over short term, medium term and long term programmes.

All this adds up to proven high reliability despite the turnaround of a brand new design in only 8 – 12 weeks depending on complexity.

Warm and inviting

PSU is proud of its capabilities and all existig and new customers are strongly encouraged to visit both the UK headquarters and manufacturing site or to be hosted on an off shore tour of the facility in south east China, the technology and capability is second to none, but just as importantly our customers are made to feel at one with PSU as a supplier, familiar with all the team and very approachable. Customers realy can readily talk to the person that designed their power supply, or the person that made it. By being so open PSU can install confidence with the people who make things happen at our customers. People are welcome at PSU.

Looking forwards

At the time of releasing this news update the company is in the middle of numerous new product releases and expects to not only post record sales again this financial year but expects the following year to see its biggest growth to date with new customers from the USA, China, Malaysia, Australia, Singapore and Europe all growing their businesses powered by PSU.

Investment, Technology and Growth

Throughout Q1 and Q2 of 2010 PSU Designs has seen a continuation of sustained growth built around the ongoing release of many new technically advanced products into many different marketplaces.  The growth has been supported by major investment in the manufacturing and testing facilities.

IFSEC Exhibition

PSU Designs chose the well-attended IFSEC exhibition at the NEC to promote several of its new fire and security products.  The company’s products and capabilities were extremely well received with multiple new business opportunities presenting themselves both in the UK and overseas.


Investment in Manufacturing

To supplement the growth, substantial investment has been made to the UK manufacturing facility.  During Q1 and Q2 a further 3 Surface Mount lines have been installed, bringing the total to 4 fully functional lines and 1 backup line.

The manufacturing process is also benefitting from high magnification vision systems to aid inspection processes and other automated machinery to aid the manufacturing process.

To aid soak testing and reliability proving, the production soak test chambers have been enhanced by the addition of 100% data logging capability.  Production soak testing now also includes the option to carry out vibration testing where deemed necessary for the product and marketplace.

Investment in Design Capability

To aid in the process of producing new designs, in keeping with the company’s philosophy of ‘right first time’, PSU Designs have trialed, approved and purchased the latest 3-Dimensional modeling software, Solid Works, provided by Solid Solutions.

New Product Releases

3 new products featuring microprocessor controls and various status indicators have been launched into the aircraft industry.  The products will help to expand the existing European markets and provide growth into US markets.

2 new DC-DC LED driver products have been launched into the vehicle lighting market.

A power supply providing a low voltage AC output has been launched into the security market.
