Tender specification sheets

Long specification
Electrical parameters have to be measured and visualised to optimise your machines' and systems' energy requirements. Only this allows analysis and, subsequently, the achievement of savings and the establishment of an energy management system. An easy-to-install solution is now available from Weidmüller. When implementing an energy management system according to ISO 50001, the Power Monitor 51A is one of the modules necessary to meet the requirements of recording, displaying and analysing power flows.
