For several years BENNING has been supplying high quantities of modular DC power Systems for business critical infrastructure within the telecommunication and information industry. These modular DC power systems are often equipped with battery back-up to protect communication systems against mains disturbances or mains power failure.
The modular system design with parallel operating hot-plug DC power modules (plug and play) provides high availability, can be upgraded and is easy to install and to maintain.


BENNING has now developed a special range of industrial modular DC power systems to meet the specifications required in the industrial sectors, such as the petrochemical industry, the power distribution and power generation industry and the automation control industry.


These systems are available for DC output voltages 24 V, 48 V, 60 V, 110 V and 220 V.
