Toroidal transformers, safety isolating transformer

RTE 330/2x18 - Discontinued types - not for new designs

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

 Safety isolating transformer according to EN (IEC) 61558-2-6

 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
