Block STEU Series Isolating Transformers
BLOCK STEU series isolating transformers with a dual input of 230 and 400 Vac, These safety transformers have a high performance for the volume due to their compact design. The transformers are quick to cable up due to the use of spring clamp terminals, they are also simple to mount with their robust metal footplate with oval slots.
Features
Dual input Voltage
Good switch on behaviour due to reduced starting currents
Excellent corrosion protection
Low Noise
Contact protected screw connection terminals complying with UVV BGV A3
Applications
An isolating transformer for safe electrical isolation of the input and out put sides. The Transformer is suitable for creating SELV and PELV because of the limit on the output voltage. The construction of the transformer can supply control systems according to VDE0113.
