CUI PDSE1-M Series 1W DC-DC Converter Modules

CUI’s PDSE1-M series of unregulated DC-DC converters are 1W-rated modules which offer high efficiency, 1.5kV isolation and thermal performance for industrial and commercial applications.

Housed in a compact, encapsulated surface-mount package, the CUI Inc. PDSE1-M devices provide precise conversion and isolation of DC rails across a range of industrial and commercial applications. The PDSE1-M converter modules are supplied in either single or dual versions offering unregulated, isolated output for loads up to 1W.

Load regulation of this series of DC-DC converters is ±20% or better, and line regulation is better than ±1.5% for input-voltage changes of 1%.

The CUI Inc. PDSE1-M modules are rated for operation over a temperature range of -40°C to 105°C. They achieve a CISPR32/EN55032, class B rating for radiated emissions with the addition of external components.
