115C Maximum Case Temperature Features POWERLINE+ -40C Minimum Temp. DC/DC-Converter UL Certified with 3 year Warranty Built-in FCC/EN55022 Class B Filter ICE 4:1 Wide Input Voltage Range Technology* Six Sided Shielded Enclosure Ribbed or Baseplate Case Styles Min. Efficiency 86% 2kVDC Isolation Low Quiescent Current 20 Watt The RPP20-W series 4:1 input range DC/DC converters are ideal for high end industrial Description 4:1 Single & applications and COTS Military applications where a very wide operating temperature range of -40C to +115C is required. Although the case size is compact, the converter contains a built-in filter EN55022 Class B / FCC Level B without the need for any external Dual Output components. The RPP20-W is available in two case styles: the ribbed case for active cooling and the baseplate case for high vibration, bulkhead-mounting or for passive cooling appli- cations. They are UL-60950-1 certified. Selection Guide 24V and 48V 4:1 Input Types (1) (2) Part Number Input Output Output Input Efficiency Range Voltage Current Current (Min.)
