Block isolation transformers of the STEU series. The BLOCK STEU series isolation transformers feature a dual input of 230 and 400 V AC. These safety transformers provide high power for their size due to their compact design. The transformers can be quickly wired thanks to the use of spring terminals and can also be easily mounted with their stable metal base plate featuring oval slots. Features: dual input voltage, good inrush behavior due to reduced starting currents, excellent corrosion protection, low noise, and contact-protected screw terminal connections in accordance with UVV BGV A3. Application area: An isolation transformer for safe galvanic separation of the input and output sides. The transformer is suitable for creating SELV and PELV due to the limitation on the output voltage. The design of the transformer can supply control systems according to VDE0113.
