STU 250/2X115

The STU 250/2X115 is an Universal control and Safety Isolating Transformer with very good switch-on behavior. It features very good corrosion protection, simple mounting and low noise. This isolating transformer is used as a control transformer for the electrical isolation of the input and output sides. The construction of the transformer to supply control systems according to VDE 0113 is designed. As a safety isolating transformer for the safe electrical isolation of the input and output sides. The transformer is suitable for creating SELV and PELV circuits because of the limit on the output voltage.
