Control- and isolating transformer

STEU 100/48

Advantages

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 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

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 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.
