Murata Power Solutions IRH-W80 250W Half-Brick Isolated DC-DC Converter
Murata Power Solutions 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 with high-efficiency levels of 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 overtemperature protection. Murata IRH-W80 DC-DC Converter is designed for railway, transportation, and industrial applications and is optimized for embedded applications on railway rolling stock environments.
