guaranteed by high quality standards.

The quality value: from design to testing The whole range of the LEVER products is designed as specified by the standards for harmonics suppression and by the new laws on electromagnetic compatibility (EMC), as provided for by the Machine Directive of the European Union (EEC) and by the International Electrotechnical Commission (IEC). Testing is an essential stage of the production process and ensures that the product fully complies with the design and targets. The Lever technicians verify the product under the supervision of the customer and/or of Certification Bodies and in accordance with the VISION 2000 standards, then draw up a set of technical reports accompanied by documented instrumental tests.

Strength and yield: our philosophy The Lever products are designed to stand the harshest operating conditions. We meet the strictest requirements in terms of reliability, efficiency and component quality, and we can also implement basically any type of customisation to meet the customer needs. Thanks to the high quality of component selection, our products can stand the most stiff environment conditions, like high temperatures, presence of salts and high humidity. To provide the highest quality standards, LEVER has achieved the ISO 9001 and IQNet certifications. Lever products have been appreciated for a long time thanks to their strength and reliability, and are designed to guarantee the continuous supply of clean power for any type of applications. The Lever converters provide exceptional reliability, with an extraordinarily long MTBF and with the adoption of the best technologies. Thanks to the DSP+PLD digital technology, to the intelligent failure detection with integrated remote signalling device, to the redundant fan pattern with air flow detection and to the doublebranch technology with advanced energy distribution, the Lever energy conversion systems can achieve extraordinary reliability levels. As they grant easy access to all the most critical components, besides, the Lever systems have a very low MTTR; this allows to considerably reduce the maintenance costs.

Lever: when organisation becomes efficiency Lever is a company specialized in the design and production of technologically advanced and innovative power converters. The company strengths are a resilient structure and the skill of its highly specialised personnel, constantly trained and accustomed to work in team to offer an increasingly efficient consultancy service. Great human resources assets and an unmatched knowhow allow the company to fulfil the customer requests by designing customised products and systems according to the technical specifications. From the research and development centre to the after-sale service, the company starts from an important assumption: the awareness of being a reference point. For this reason the company is divided into different specialised area, constantly in contact with each other: - sales office - technical/sales office for offer engineering - administration office - technical office - R&D department for the development of new products - after-sale service - purchasing office - production and testing - quality control - warehouse/logistics

The numbers that make the difference Let’s have a look at the numbers: LEVER has two production centres, organised by specialisation area and production type. Production centre: - 4,300 sq m Production and material storage - 800 sq m offices - 500 sq m Testing room Our company has recently expanded, adding new offices to the facility.

High flexibility, allowing our equipment to adapt to all system features The DPS is suitable for a wide range of applications in the most demanding industrial environments. It allows to achieve complex system architectures to ensure maximum power availability with a wide range of accessories and optionals. We can supply redundant N+1 or HOT STANDBY configurations. Thank to the new LEVER DIGITAL TECHNOLOGY, you can choose different alarms with voltage-free contacts, with a wide range of LED indications and accurate digital measurements. Furthermore a graphical display, shows measurements, alarms and a one-line diagram to help the operator to better understand the situation. The digital inputs can be customised according to specific customer needs, allowing to take into account special system statuses and to display them on the monitor. The display can store the alarm list and an event history. You can adapt the DPS to the technical specifications. Should you need any particular applications and customised solutions, please contact LEVER.
