Control- and isolating transformer
STU 1600/2x115
Characteristics
Benefits
› Universal input voltages 210 to 540 Vac
› Very good switch-on behaviour thanks to reduced starting currents
› High power density due to a compact construction design
› 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
