Block STEU Transformers 230V and 400V to 2 x 12V

Block Brand: Block

The Block STEU Transformers 230V and 400V to 2 x 12V are low power on current control, safety, or isolation transformers with tension spring clamps and dual purpose foot plate for screw and rail mounting (TS-35 rail to 250 VA) as per DIN 50022. Designed with a very good switch-on behaviour thanks to reduced starting currents, plus high performance for the volume thanks to compact design, these high quality transformers also have excellent corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation.

  • Contact protected screw connection terminals - comply with UVV BGV A3
  • Simple mounting - robust metal footplate with oval slots
  • Natural cooling
