Low profile transformer, isolating transformer
FL 42/24
Characteristics
General data
The PCB transformers of the FL series impress with minimal height and maximum power density. With dual input and output coils, the transformers can be configured for series or parallel connections. Mounting is done using screw fastenings in the base plate.
Benefits
