Control- and isolating transformer
STEU 320/48
Characteristics
Benefits
› Dual input voltage 230 and 400 Vac
› Very good switch-on behaviour thanks to reduced starting currents
› High power density due to a compact construction design
› Primary side ±15 V tappings for voltage adjustment
› Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation
› Quick to cable up thanks to the use of spring-clamp terminals
› Contact protected screw connection terminals complying with UVV BGV A3
› Simple mounting thanks to robust metal footplate with oval slots
