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.
