Control- and safety isolating- resp isolatingtransformerSTEU

General Data

Rated input voltage 230 and 400 Vac

Rated output voltage 24 - 230 Vac

Rated power 63 - 2500 VA

Insulation class B

Maximum ambient temperature 40 degC

Efficiency up to 94

Degree of protection IP 00

Advantages

Dual input voltage 230 and 400 Vac

Very good switch-on behaviour thanks to reduced starting currents

High performance for the volume thanks to compact design

Primary side plusmn15 V tappings for voltage adjustment

Very good corrosion protection and low noise thanks to BLOCKIMPEXvacuum 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 outputsides The construction of the transformer to supply control systems accordingto VDE 0113 is designed

As an isolating transformer for the safe electrical isolation of the input andoutput sides The transformer may be used to set up protective separation as aprotective measure in accordance with VDE 0100

As a safety transformer for the safe electrical isolation of the input and outputsides The transformer is suitable for creating SELV and PELV circuits becauseof the limit on the output voltage
