Control- and isolating transformer

STEU 160/11 - Discontinued types - not for new designs

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

 With combination footplate for bolted and rail mounting
