Toroidal transformers, separating transformer
RKD 20/2x24
Characteristics
General data
The toroidal transformers of the RKD series enable space-saving use due to minimal size with maximum performance. The low magnetic stray field does not affect surrounding components and ensures excellent temperature behavior. The connections can be soldered directly onto a PCB.
Benefits
› Separating transformer according to EN (IEC) 61558-2-1
› Lightweight
› Dual input and dual output coils for series or parallel connection
› Minimal no-load losses
› Very low noise field
