The FL type resin moulded safety isolating transformer, with
its extremely low profile is most suited for printed circuit
boards as well as 19" rack systems.
The use of two chamber glass-fibre reinforced polyamid bobbins
and the immersion in resin enables a HV test of 5000 V ac
to be carried out.
The transformer can be secured with self tapping screws
2,9 x 9,5 mm DIN 7981 (as extras available). This can be an
advantage when the transformer is soldered, via soldering
bath, to a printed circuit board, because no extra space,
which is precious, is needed to secure the transformer to the
PCB and pollution of the soldering bath is averted.
The input and output windings are dual and separated from one
another so that the input windings must be connected in parallel
for 115 V and in series for 230 V. The dual output can be
operated in series or parallel.
Note :
* vacuum epoxy resin moulded
* self extinguishing epoxy resin UL 94 V-0 listed
* also available in all self extinguishing materials
according to UL 94 V-0
* minimal difference between load and no-load voltage
* high electrical efficiency
