The RPA40-11005SFR from Recom Power is an Isolated Buck DC-DC Converter that converts an input voltage of 36 – 160 V to an output voltage of 5 V.  This DC-DC converter delivers an output power of 40 W and has an efficiency of 88%. It includes a reinforced isolation barrier rated up to 3 kVAC/1min and offers high power density, no minimum load, tight regulation, low ripple/noise figures, and trimmable outputs. This RoHS-compliant DC-DC converter includes built-in under-voltage lockout protection (UVLO), over-temperature protection, short-circuit protection, over-current protection (OCP), and over-voltage protection (OVP) to prevent short-circuit and over-load-related damages. It is available in a through-hole package that measures 56.4 x 36.83 x 15 mm and is ideal for rolling stock rail and other commercial applications.
