Low profile safety transformer
Low profile safety transformer according to IEC/EN61558-2-6 suitable for general applications with double or reinforced insulation – max. output voltage: 50 V. E.g. electrical isolation for use in devices, built according to VDE0805/EN60950 regulations.
Specifications
- Ultra flat PDB type transformers for use in ultra small power supplies.
- Short-circuit proof construction.
- Transformer completely sealed with polyurethane varnish in polyamide mold.
- Additional fixing with 4 screws 2.9 x 9,5 e.g. DIN7981 possible.
- PTF-UI39 transformers can be customer-specified, e.g. output characteristics, temperature rise for nominal operation/ open-circuit, PRI/SEC voltages, pinning.
