Specifications (Core Operating Area)
The RW series with 2:1 input voltage ranges and max. height of 7,0 mm has been designed for the telecom -
and industrial automation markets. They are particularly aimed at applications where pcb-space is at a premi-
um, still requiring industrial standard pinning.Also an optional SMD pinning is available. The converters sup-
ply the full 3 Watts without additional heat-sinks over the temperature range -40C to +80C.
