Control- and safety isolating- resp. isolating transformer
STE 100/23/24
Advantages
Very good switch-on behaviour thanks to reduced starting currents
High performance for the volume thanks to compact design
Primary side ±5 % tappings for voltage adjustment
Very good corrosion protection and low noise thanks to BLOCKIMPEX
vacuum impregnation
Quick to cable up thanks to the use of spring-loaded 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.
