ST 63/23/23 Block

Control- and safety isolating- resp. isolating transformer ST 63/23/23 Advantages Very good switch-on behaviour thanks to reduced starting currents High performance for the volume thanks to compact design Primary side 5 % tappings for voltage adjustment Very good corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation Contact protected screw connection terminals complying with UVV BGV A3 Simple mounting thanks to robust metal footplate with oval slots Applications 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 an isolating transformer for the safe electrical isolation of the input and output sides. The transformer may be used to set up protective separation as a protective measure in accordance with VDE 0100. 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.
