+115C Maximum Case Temperature Features -45C Minimum Case Temperature Built-in EMC Filter DC/DC Converter Ribbed Case Style ICE 2250VDC Isolation Wide 4:1 Input Voltage Range Technology* RPP20-2412DW EN-55022 Class B Description 20 Watt 4:1 The RPP20 series 4:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military 1.6 x 1 applications where a very wide operating temperature range of -45C to +115C 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. Ribbed Style Dual Output Selection Guide Part Input Input Output Output Efficiency Max.
