RALE Design Software consists of FOUR professional programs designed to calculate a wide range of transformers, autotransformers, and inductors:
1) RALE Design Software for small transformers,
2) RALE Design Software for toroidal transformers,
3) RALE Design Software for large transformers and
4) RALE Design Software for small chokes & inductors.
When you rent our Software, your package contains all of these RALE Design programs.
Thanks to many years of investment of time (>40 years) and knowledge in its development, RALE Design Software has become a powerful tool for more than 200 manufacturers of transformers and inductors around the world (see List of Users in the Menu).
See our list below with the wide range of transformers and inductors you can design with RALE Design Software.
Check out our FREE information and know-how for transformer and inductor design by clicking on DESIGN EXAMPLES in the Menu.
