Description
40 Watt 4:1
2“ x 1.2“
Ribbed Style
Single Output
The RPP40 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 RPP40 is available in a ribbed case style for active cooling. They are UL-60950-1 certified.
