Description
The RPP20 series 4:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military
applications where a very wide operating temperature range of -45°C to +115°C is required. Although the case size
is very compact, the converter contains a built-in EMC filter EN-55022 Class B without the need for any external
components. The RPP20 is available in a ribbed case style for active cooling. They are UL-60950-1 certified.

* ICE Technology
ICE (Innovation in Converter Excellence)
uses state-of-the-art techniques to minimise
internal power dissipation and to increase
the internal temperature limits to extend the
ambient operating temperature range to the
maximum.
