Product Overview

• Product Overview

  As a control transformer for the electrical isolation of the input and output sides. The construction of the transformer is designed to supply control systems according to EN 60204. 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 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.

  • Dual input voltage 230 and 400VAC
  • Very good switch-on behaviour thanks to reduced starting currents
  • High power density due to a compact construction design
  • Primary side ±15V tappings for voltage adjustment
  • Very good corrosion protection and low noise thanks to BLOCK IMPEX 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
  • DIN rail clamp included up to 250VA
