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.
