PCB mounting low voltage mains transformers with a single 230 or twin 115 VAC 50/60Hz primary winding.
The two independent secondary windings may be connected in series or parallel to give a wide range
of output voltage and current options
- PCB mounting low voltage mains transformers with a single 230V 50/60Hz primary winding
- Thermal fuse in primary providing overload and short circuit protection
- Flame retardent materials to UL94-V0
- Independent secondary windings suitable for series/parallel connection to give a wide range of output voltage and current options
- Double section metric bobbin construction
- Fully shrouded windings
- Full varnish impregnation
- 100% electrical and flash tested
- Extra pins for secure board mounting
