Dynamic Uninterruptible Power Supply systems

EURO-DIESELEURO-DIESEL is a global specialist in Dynamic Uninterruptible Power Sup-ply (UPS) systems and generator sets, founded in the mid nineteen-eighties, and located in the heart of Europe in Liége, Belgium.

EURO-DIESEL and CUBIC have been partners through many years and have a history that dates nearly 20 years back. CUBIC supplies the modular enclosures for the switchboards ap-plied as a part of the various types of UPS systems.

New testing facilitiesTo remain in the position as a global specialist in the supply of UPS sy-stems, EURO-DIESEL has recently in-augurated a state of the art production and testing facility. With the new facility, EURO-DIESEL now holds the world’s largest UPS facility with a surface area of around 6300 m².

The new facility does not only include production area but also an impres-sive R&D and testing area with bays equipped with high-end testing and measurement equipment to demon-strate the consistent performance of the NO-BREAK KS® systems.

The UPS systemAn Uninterruptible Power Supply (UPS) system is a unit that provides power to a load when the input power source, typically the utility mains, fails. An UPS differs from an auxiliary/emergency power system or standby generator by providing instantaneous or near-

instantaneous protection from input power interruptions by means of one or more attached units.

Around the world, one will today find many different systems and alterna-tive UPS technologies to solve the problems linked with continuity of power supply. At EURO-DIESEL, the technology of dynamic UPS systems is applied.

EURO-DIESEL has taken an innovative and advanced Dynamic Uninterruptible Power Supply system (D-UPS) to the market named the “NO-BREAK KS®”. The ingenious design of this unique product has resulted in a rapid growth of the business and today EURO-DIE-SEL employs over 80 engineers and technicians in Belgium, keeping them in the lead of the D-UPS technology.

NewsThe no-break systemsEURO-DIESEL’s NO-BREAK KS® Dyna-mic UPS systems provide the user with multiple benefits:

• No power electronics: The sine wave is generated by a synchronous machine • No need for battery banks requiring separate rooms • High short circuit current capability • Reduced voltage distortion in case of short circuit • No harmonics generation • No transfer of mains harmonics to the secured load, neither of harmo- nics generated by the load to the mains • Intrinsic reliability due to simple design with lowest component count • Compact physical size – small foot print • Largest single module available - 3000 kVA • Unlimited paralleling possibilities • No air conditioning requirement: Ventilation only

The highlight of EURO-DIESELs product range is the NO-BREAK KS® at 3000 kVA being the world’s first UPS of such a capacity. The NO-BREAK KS® has been the trademark and core business of the company since the 1980s, with the first system, the NO-BREAK KS1® developed at 330 kVA.

The new 3000 kVA is designed for operation within regions around the world operating at 60 Hz in stand-alone and parallel redundant configu-rations, whilst a 2500 kVA version is also available for 50 HZ applications.

With the introduction of the new 3000kVA NO-BREAK KS®, EURO-DIE-SEL has taken the lead in the UPS industry by offering the most compre-

hensive range of power ratings and output configurations.

The system also provides tailored and engineered solutions for the demands of the data centre industry and mission critical applications requiring multi MVA of secure and uncompromised power.

These various types of the system can also be configured as Dual Out-put Systems, the NO-BREAK KS®-SB, where the division between critical and essential loads can be customised, up to its total maximum output power capacity.

Considering the high power ratings of these modules, many of the project applications will typically be at medium voltage but the system is also available in low voltage versions.

EURO-DIESEL product applicationThe NO-BREAK KS® product range has during the years been used as back up system in many different projects. A selection of these is: • Sensitive production units semiconductors, textile, aluminium, pharmaceutical industry, plastics.• Bank and Finance protection of data centres, stock exchange.• Airports runway lighting, passenger termi nals, radio communication.• Internet and corporate data centres call centres, data hotels.• Television and telecommunication recording studios, satellite tele communication.• Hospitals: emergency rooms, surgery rooms.

• High tech applications and sciences particle accelerators, weather forecast centres, research centres.• Road and rail protection of tunnels, railways signalling.

CUBIC switchboardsFrom the very beginning, EURO-DIE-SEL has been a good and loyal CUBIC customer and partner. We at CUBIC Belgium and the engineers from EURO-DIESEL have always worked together to find the best solutions for their NO-BREAK KS® panels.

The most of the panels are Form 4a or 4b , the main busbar from 2000A to 4000A , 50-80-100kA.

The new panel for the test facilities was one of the most complex panels that we have made together. It was thanks to our good collaboration and a lot of working hours that we succeeded.
