Murata IRH-W80 250W half brick isolated DC-DC converters

The IRH-W80 250W half brick isolated DC-DC converter provides a 250W single output from an ultra-wide input voltage range of 16VDC to 160VDC, complying with input battery voltage transient ranges per EN50155 (2017). This isolated, regulated converter module comes in an industry-standard half brick package that offers high-efficiency levels up to 91%. The fully isolated (4242VDC) module accepts a wide input voltage range while maintaining a fully regulated single output. The output voltage offers overvoltage, overcurrent, short circuit, and over-temperature protection. This converter is designed for railway, transportation, and industrial applications, and is optimised for embedded applications on railway rolling stock environments.
