1AC PCB Transformer, uncovered version, encapsulated coilPT 0.8 - 56VA to IEC/EN61558-2-4/-6

overviewtechnical dataPDF data sheet

Isolating Transformer

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

Safety Transformer

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

Specifications

  • Connections: PCB with solder pins Ø 0.8mm. Recommended board mounting holes: 1.2mm.
  • Encapsulated coil (mounting according to protection class II or III ready) allows mounting of other components close to the transformer.
  • Due to innovative vacuum impregnation in polyester varnish, the noise level is extraordinary low.
  • Any mounting position or angle possible.
  • Version 0.8/-1.5 VA construction determinded short circuit proof. Short-circuit proof design for other versions with higher load on request (combined with external fuse and built-in temperature limiter)
  • Catalog mentioned lead-wire spacing and pin assignment is standard.
  • We recommend bold distance mounting for sizes > 4.4VA.
  • To improve mechanic foothold on the boards additional solder pins can be attached to the transformer – on request.
