Toroidal transformers, isolating transformer
RTE 120/2x24
Characteristics
General data
The toroidal transformers of the RTE series enable space-saving use due to minimal size with maximum performance. The transformers feature overload protection thanks to the built-in thermal fuse and have a lightweight design. The connections can be soldered directly onto a PCB.
Benefits
› Isolating transformer according to EN (IEC) 61558-2-4
› Dual output coils for series or parallel connection
› Minimal no-load losses
› Excellent temperature behavior due to low magnetic stray field
› Very low noise field
