Efficiency 86% 3kVDC Isolation Low Quiescent Current 50 Watt Description 2:1 Single The RPP50 series 2:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military applications where a very wide operating temperature range of -45C to +120C is required. Although the case size is very compact, the converter contains a built-in filter EN55022 Class B / FCC Level B wit- Output hout the need for any external components. The RPP50 is available in two case styles: the ribbed case for active cooling and the baseplate case for high vibration, bulkhead-mounting or for passive heatsink cooling applications. They are UL-60950-1 certified. Selection Guide 24V and 48V Input Types (1) (2) Part Number Input Output Output Input Efficiency Range Voltage Current Current (Typ.)
