Applications
Liquid-cooled transformers of the Schmidbauer WKT series are excellently suited for water-cooled inverter technology. A potential-free water cooling simplifies water cooling in the entire system.
Description
The input voltage is 3x 400V at 50 / 60Hz and can be customized.
The number of cooling circuits, the prescribed water inlet pressures and water temperatures depend on the mode of operation and the characteristics of the load.
