Tender specification sheets

Long specification
Electrical parameters have to be measured and visualised to optimise your machines' and systems' energy needs. This is the only way in which an analysis can be carried out and, subsequently, savings made and an energy management system established. An easy-to-install solution is now available from Weidmüller. When implementing an energy management system according to ISO 50001, the Power Monitor is one of the modules necessary to meet the requirements of recording, displaying and analysing power flows.
