Laminated Transformers
SIGA design and manufacture a range of bobbin wound laminated transformers with power output range extending from 1VA up to 5kVA at a supply frequency of 50Hz.
All SIGA laminated transformers can be designed to conform to the latest safety standards e.g. EN60601, EN60950 and EN61558.
The main dimensions of the transformer are given in the table below along with the approximate power ratings and regulation figures. The difference between the styles is mainly that of mounting method and the basic styles are :-

Within these main styles of bobbin wound laminated transformer other options are available, subject to the size of the transformer and type of assembly. Terminations – can be flying leads, bobbin mounted terminals, terminal boards or terminal blocks. Bobbins – can be single or double sections, with or without shrouds. Particularly with double section bobbins the use of full shrouds provides an increase in creepage and clearance distances. The standard finish is varnish coating and if required an additional coat of enveloping varnish can be applied to provide extra protection against moisture.
The table below shows the approximate dimensions for the different ratings. The depth “D” does not include for the pins and approximately 7mm should be added each time where terminals are found.
