Murata Power Solutions IRQ-W80 & IRH-W80 Input DC-DC Converters

Murata Power Solutions IRQ-W80 & IRH-W80 Input DC-DC Converters deliver 150W/250W output power from an ultra-wide input voltage range. The IRQ-W80 converter complies with 24V to 110V and the IRH-W80 converter complies with 16V_DC to 160V_DC input voltages, including transients as per EN50155 (2017) standards. The converters come in a fully encased industry-standard quarter-brick package with 16V_DC to 160V_DC input voltage and 12V, 24V, or 54V output voltage. The diode rectifier topology and fixed frequency operations result in efficiencies of up to 89% (IRQ-W80) and 91% (IRH-W80). Murata IRQ-W80 DC-DC Converter is designed to meet all UL and IEC emissions, safety, and flammability certifications. Typical applications include industrial, railway, and transportation.
