overviewtechnical dataPDF Data Sheet

1 phase control transformer

according to IEC/EN61558-2-2 for power supply of control circuits in machinery, terminal blocks (VDE0113/ EN60204).

Isolating transformer

according to IEC/EN61558-2-4 for general applications, e.g. electric (galvanic) isolation for devices according to VDE0700/ EN60335.

Safety transformer

according to IEC/EN61558-2-6 for general applications with double or enhanced insulation and max. 50V output voltage, e.g. electric (galvanic) isolation for devices according to VDE0805/EN60950.

Specifications

  • Due to the use of high quality insulating materials and special insulation design, ST series can be used as control-, isolating or safety transformer.
  • Our UL insulation system guarantees global application possibilities.
  • Inrush currents and short circuit behaviour are optimised for use with motor-circuit switches, especially equipped with primary circuit thermal or magentic switching functions.
  • Transformers are fully vacuum impregnated.
  • Screw terminals contact proof according to VBG4.
  • For voltage adjusting purposes, primary winding offers taps at ±5% of nominal input voltage.
  • Transformers are protection class I ready.
  • 2 blade terminals 6.3 x 0.8 for ground wire connection.
  • Mounting via angle brackets, any mounting position or angle possible.
