The name of Borri Power was introduced to the UK and Middle East and American markets in the late 1970‘s by W A Technology Group engaged by the Italian Borri family and Cyberex to develop the international export business.
The brand name of “Borri Power” has been in continuous by our associated companies W & A Technology Group and Power Systems International Limited since 1985.

Please note: Borri Power Systems Limited, Borri (UK) Limited and Power Systems International Limited have no connection with the new Borri SpA company formed by the directors of Astrid Energy Enterprises SpA in 2005.

Our market focus is on supplying industrial grade standardised UPS systems in two product ranges:

  The EF20 series

  This is a new product range with single phase input or three phase input with single phase output from 5kVA to 25kVA.

  This range of industrial grade UPS systems is available with single phase input and single phase output in sizes up to 25kVA, an alternative version with three phase input is also available. The use of high frequency pulse width modulation (PWM) inverters ensures exceptional performance and extremely quiet operation. An important feature of this product is the automatic input power factor correction and harmonic compensation technique built into the rectifier, thus the total harmonic distortion reflected into the input power source is very low and the current consumption is optimised.

  The RT 20 series

  A rugged transistor product range using conventional logic with a three phase input with single phase output UPS systems up to 150kVA and with three phase input and three phase output from 10 kVA to 400 kVA.

  Industrial grade compact, fully configured integrated style of UPS systems available with 6 pulse or 12 pulse rectifiers, available in single module and multi module parallel configuration for installation in computer room or plant room. The inverter design is a high frequency PWM type with shielded logic, output isolation transformer, static interrupter with static transfer and manual bypass switch, a status indicating and alarm mimic with digital metering is fitted as standard. This product design has adopted the commercial standard DC bus voltage of 384 and can be used with all types of batteries. The VRLA batteries can be supplied for assembly onto racks or are supplied in enclosures to match the UPS enclosure. Available in sizes, 10kVA to 150kVA with single phase output and 10kVA to 400kVA with 3 phase output. The RT20 range of products can also be supplied with 60Hz output or used as frequency converters.

Borri Srl Elettronica Industriale was the Italian licensee of Cyberex Inc USA and manufactured their thyristor PWM inverter industrial UPS designs for the petrochemical engineering EPC companies and other industrial markets.

The W & A Technology group was involved in the development of a new technology range of transistor PWM inverter UPS systems, subsequently manufactured in Italy, the products were sold in the UK and the EMEA Region by Cyberex International Limited and in the USA by Cyberex Inc. Mentor Ohio

W & A Technology subsequently took over the international marketing of the new licenced UPS product range from Cyberex International Limited and established Borri Power Systems Limited and power Systems International Limited to extend the export marketing operations.

The Borri family sold their Borri Srl Elettronica Indstriale company to General Signal Corporation in 1990. then sold to SPX, after a very short period, SPX sold the Borri company to the UK firm BTR PLC. BTR was the owner of Exide, Best Power Technology, Deltec, Gould, Prestige, Fiskars and Powerware UPS systems. BTR became Invensys PLC and the Borri Italian firm lost its identity when it was renamed Invensys Power Systems SpA.

The name was changed again to Powerware SpA. Invensys PLC sold their Powerware businesses in August 2004 to Eaton Corporation and the Powerware SpA company name was changed to Eaton Power Quality SpA.

In January 2005 Eaton Corporation offered their Italian subsidiary for sale, thus after a somewhat turbulent period of instabilty and uncertainty over the preceding 10 years it was sold to local investors in September 2005.
