Seleta is a small company which designs, manufactures and maintains Power Supplies and Uninterrupted Power Supplies of various characteristics and applications. Due to its manufacturing capabilities, the company assembles also personal computers, servers, workstations and SIMMs. It provides PCB manufacturing services, both in traditional and SMD technologies, under customers' design and specifications.

The company employees 15 people, 8 of which are involved in electronics. The annual turnover is 1.65 MEuro. Its main industrial sectors are: 31: Electrical and 30: office machinery , computers.

For the product subject of the experiment, Seleta delivers mainly to the South Italian market where it holds about 2% of the total, while in Northern Italy and Europe SELETA position is completely marginal.

The actual analog UPS is not any more competitive, because the global performances do not match anymore with the market demand (a PC remote control of the UPS) and competitors have digital solutions. Therefore the image of a 'digital' or 'microcontroller-based' UPS is a mandatory for the marketing to re-launch the sales.

The purpose of the AE has been the design of a new digital UPS with a PC remote control, allowing production costs reduction, leveraging of the selling price and a market share increase for the company.

The main results of the experiment have been therefore:

  • Technical: to acquire digital design competencies and to use such knowledge to develop new, more performant, control circuitries;
  • Economical: an increase of 70% of the FU market share is forecasted. A saving of 23% on the production cost, an increase of the selling price from 0.45 to 0.55 EUR/W.

The AE costs has been of 36.4 KEuro, with a 8 months duration. The payback period is of about 6 months, with a ROI of 550%.

Additional benefits achieved through this experiment have been:

  • acquiring of technical project management capabilities;
  • personnel skills improving from pure analog to microcontroller based solutions;
  • possibility of re-using the same techniques for the new SELETA product lines such as the on-line UPS, which represents the most challenging product of the company to be launched.

Detailed information

You can also benefit from microelectronics

Microcontroller technology provided SELETA with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
