Control- and isolating transformer
ST 320/11/11 - Discontinued items – not for new applications
Characteristics
Benefits
› Very good switch-on behaviour thanks to reduced starting currents
› High power density due to a compact construction design
› Primary side ±5 % tappings for voltage adjustment
› Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation
› Contact protected screw connection terminals complying with UVV BGV A3
› Simple mounting thanks to robust metal footplate with oval slots
