USTE250/2X12 Block

Universal control- and safety isolating- resp. isolating transformer USTE 250/2x12 Advantages Universal input voltages 208 to 600 Vac Very good switch-on behaviour thanks to reduced starting currents High performance for the volume thanks to compact design Very good corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation Quick to cable up thanks to the use of spring-loaded terminals Contact protected screw connection terminals complying with UVV BGV A3 Simple mounting thanks to robust metal footplate with oval slots Up to 250 VA with combination footplate for bolted and rail mounting 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.
