Summary

DescriptionCurrent-transformer-21 hg.jpg	English: A fully enclosed 250 VA autotransformer (spartransformator in German) for 110⇔230 V conversion. An autotransformer does not provide isolation of primary and secondary sides, but allows significant savings in the amount of copper (hence spar in its German name). This one is made by Block Transformatoren-Elektronik GmbH, a German family business from Verden (Lower Saxony). Their primary plant is still based in Verden, although they also distribute American and Chinese products [1] Deutsch: Ein 250VA, 110V/230V spartransformator von BLOCK Transformatoren-Elektronik GmbH
