Since our company’s founding in 1888, our quality products in the field of electrical engineering and mechanical engineering and construction have been internationally established.
We have got more than 90 years of experience in the field of safety power supply. In 1916, Ruhstrat built the first emergency lighting system for places of assembly. As a competent supplier of battery-assisted power supplies, we specialize not only in modern safety lighting systems but also in DC power supplies, battery-assisted central power supply systems (BSV – previously ZSV) as well as uninterrupted power supplies (UPS). Ruhstrat’s BSV / ZSV devices are used for surgical lighting and critical medical devices in hospitals. Our USV devices maintain power supply in industrial plants and in computer networks.
We provide end-to-end solutions and support from planning to installation. Moreover, we supply anything from a single source, provide immediate replacement and, if required, offer service and maintenance. We are happy to meet customer requests as well as the most difficult technical requirements. The installation, maintenance, and condition of a safety lighting system are governed by a large number of rules and regulations that are interlinked by references. This concerns both lighting and electrotechnical issues. This concerns both lighting and electrotechnical issues. Many German rules and regulations which had been effective in the past have more recently been revised or replaced by European rules and regulations.
The most important installation guidelines concerning safety lighting systems for electrotechnical requirements are DIN EN 50172 norms (VDE 0108-100), design DIN VDE 0108-100 norms and DIN VDE 0100-718 norms. These electrotechnical regulations are supported by a set of photometric parameters stipulated in DIN EN 1838 and DIN 4844 norms (or ISO 3864). The regulations according to EN 60598 part 1 and EN 60598 parts 2-22 contain general requirements for luminaires as well as emergency lighting. These are crucial for producers regarding the electrical, thermotechnical, and mechanical safety of the luminaires.
