The custom toroidal power transformer range is suitable for all normal transformer applications and covers a range of power outputs from 1VA up to 10kVA when operated from a 50Hz power supply. Transformers can also be supplied for use on 60Hz and 400 Hz supplies.
SIGA transformers are designed and manufactured to optimise the inherent benefits of the toroidal type of construction, resulting in increased efficiency, reliability, reduced core losses and radiated field. The range of core sizes available allows the designer greater scope to meet the customers’s dimensional requirements.
SIGA transformers can also be supplied complying with the requirements of a number of international standards- typically EN61558, EN60950, EN60601 and UL506.
The standard covering is a clear polyester tape finish, which is suitable for most protected indoor environments. For humid conditions protection against moisture can be achieved with vacuum varnish impregnation and if necessary the application of one or more coats of the enveloping varnish.
SIGA can also supply non-standards types of termination, fixing and finish, and will be pleased to discuss any special requirements.
SIGA also supply the following:
Standard toroidal transformers,
Bobbin wound laminated transformers, Ferrite cored transformers,
Potted transformers, Medical isolating transformers,
Foil wound coils and special assemblies.
