With an ultra wide input voltage range of 16-160VDC, the RUW series is capable of withstanding surges from 24,36,48,72, 90 and 110V systems, largely eliminating the requirement for input protection circuitry. Optional features include a Power Fail/DC OK signal and circuitry to facilitate long hold-up times with a small external capacitor across ±Vint pins.

RoHS COMPLIANCE INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. The pin termination finish on this product series is a Gold flash (0.05-0.10 micron) over Nickel Preplate. The series is backward compatible with Sn/Pb soldering systems. Tinned tabs are provided along the case edges to provide mechanical support through slots in the PCB. Hand soldering of these tabs may be necessary to ensure satisfactory joint quality.

The graph below shows the approximate hold-up time for a given capacitance. The active hold-up feature typically requires 60 seconds to fully reset between supply interuptions. Capacitor voltage rating should be 100VDC minimum. 120 100 80 60 40 20 0 0 100 200 300 400 500 600 700 800 900 VINT Capacitor (μF) Power Fail Warning Details The optional Power Fail/DC OK signal gives an advance warning of loss of output after input failure (typically 2ms) and an indication that the output voltage is within specification. www.murata-ps.com/support KDC_RUW15.A01 Page 3 of 5 RUW15 Series Isolated Ultra-Wide Input DC/DC Converters THERMAL DERATING GRAPHS RUW15SL12HC -40 14 12 12 12 12 10 10 still air 88 100 lfm 66 200 lfm 44 400 lfm 22 00 -40-40 20 -20 02 0 04 06 20 08 40 01 10 10 still air 8 8 100 lfm 6 6 200 lfm 4 4 400 lfm 2 2 0 0 00 100 RUW15SL24C Available Power Available Power -40 14 -40-40 20 -20 02 0 04 06 20 08 40 01 00 100 RUW15SL24HC -40 14 -40 14 12 12 12 12 10 10 Available Power Available Power RUW15SL12C still air 88 100 lfm 66 200 lfm 44 400 lfm 22 10 10 100 lfm 66 200 lfm 44 400 lfm 22 00 00 -40-40 20-20 02 0 04 06 20 08 40 01 00 100 still air 88 -40-40 20 -20 02 004 0620 08 40 01 00 100 EFFICIENCY GRAPHS RUW15SL12HC 90 90 70 70 50 110V 24V 48V 72V 30 10 Efficiency (%) Efficiency (%) RUW15SL12C 50 24V 48V 72V 110V 30 10 0 0 0 10 20 30 40 50 60 70 80 90 0 100 10 20 30 40 RUW15SL24C 60 70 80 90 100 RUW15SL24HC 90 90 70 70 50 24V 48V 72V 110V 30 10 Efficiency (%) Efficiency (%) 50 Load (%) Load (%) 50 24V 48V 72V 110V 30 10 0 0 0 10 20 30 40 50 60 70 Load (%) 80 90 100 0 10 20 30 40 50 60 70 80 90 100 Load (%) www.murata-ps.com/support KDC_RUW15.A01 Page 4 of 5 RUW15 Series Isolated Ultra-Wide Input DC/DC Converters PACKAGE SPECIFICATONS Mechanical Dimensions PIN CONNECTIONS 50.80 (2.0) 50.80 (2.0) Pin Function 1 2 3 4 5 6 7 8 REMOTE ON/OFF† -VINT* * +VINT -VIN +VIN * PF/DC OK +VOUT -VOUT Weight: 105g Typ.
