Universal control- and safety isolating- resp. isolating transformer

USTE

General Data

Rated input voltage 208 - 600 Vac

Rated output voltage 24 - 230 Vac

Rated power 100 - 3200 VA

Insulation class B

Maximum ambient temperature 40 °C

Efficiency up to 96 %

Degree of protection IP 00

Advantages

Universal input voltages 208 to 600 Vac

Very good switch-on behaviour thanks to reduced starting currents

High performance for the volume thanks to compact design

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 isolating 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.
