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 :-
Horizontal Printed Circuit Board mounting assembly. Although intended for mounting using the PCB pin terminations, larger sizes have corner holes for additional fixings.
Clamping type assembly providing two hole fixing. Used on small and medium size transformers.
|STYLE 3: Universal end frame assembly, which offers 4 hole fixing and is suitable for the larger sized transformer.|
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.
