Murata Power Solutions IRV300 series chassis-mount isolated DC-DC converters

Mixed Media

The IRV300 series is a 300W stand alone, system level, chassis mount isolated DC-DC converter. The converter features an ultra wide input designed to accept nominal battery voltages from 24V to 110V in a single product. The IRV300 is ideally suited for Railway applications, meeting EN50155 standard in a single package. The output voltage has a wide trim range up to +15% of Vnom, and features a constant current output profile ideally suited for high inductive/capacitive loading. They feature programmable undervoltage lock- out (PUL) to prevent deep discharge of the input batteries, remote ON/OFF control and an open collector DC output power good signal including a visual LED as standard. The IRV300 offer additional options such as “Hold Up” capability for overriding load dependent input interruptions of 10mS to 20mS not affecting the output and “ORing FET” for dual redundancy or power share incorporating droop voltage. The standard self protection features include overvoltage protection, current limit/short circuit protection, over temperature protection and ensure safe and reliable power delivery.

The IRV300 series from Murata Power Solutions is a 300W stand alone, system level, chassis mount isolated DC-DC converter.
