| RUHSTRAT variable column transformers are manufactured according to DIN VDE 0552. Due to their low power loss RUHSTRAT variable column transformers work economically and have a low energy consumption. The high quality of our variable column transformers is proven by their unique construction and allows a long service life and high reliability.
