clearances and creepage distances allow operation in
pollution degree 3 environment (with AC input). All board
assemblies are coated with a protective lacquer.
The thermal concept allows operation at full load up to an
ambient temperature of 60 °C (LW models) or 70 °C (EW
models) in free air without forced cooling. A rugged DIN snap-
fit device allows easy and reliable fixing onto the various 35
mm DIN rail models. The converters are fitted with cage clamp

R-input not connected.
For derating at low input voltage see section Output Power Derating.
For minimum quantity and lead times contact Power-One.
The converters have been tested up to 440 Hz; for operating frequencies <47 Hz or >63 Hz contact Power-One.
On double-output models the options R, M2, D1, D2, D5 are related to the second output only.
Improved EMC performance for LWN/LWR models. Former models without E are still available on request.
