1AC Isolating Transformer with Static Shielded WindingTTN 0.025 - 0.25kVA according to IEC/DIN EN61558-2-4

overviewtechnical dataPDF data sheet

Typical applications

Flush mounting isolating transformer for safety application “mains breakup”.

Definition

Device protection used in normal or harsh environment. Electrical equipment must be disconnected from mains power network, protected active parts of equipment not grounded.

Specifications

  • Special winding construction (1 chamber with shielded winding between PRI and SEC) allows excellent attenuation of mains failures (symmetric/ asymmetric) in SEC circuit.
  • Shielded winding delivery status: Common grounding connected to transformer core.
  • Standard voltages: PRI 230 V and SEC 230 V.
  • Voltage range PRI 100 V – 600 V and SEC 12 – 400 V on request.
  • Due to innovative vacuum impregnation in polyester varnish, insulation stability is very high; the noise level is extraordinary low.
  • Screw terminals contact proof according to VBG4.
  • TS35 DIN rail mounting.
