Murata IRH-W80 series converter

The IRH-W80 series of isolated regulated converter modules, deliver an impressive 250W single output from an ultra wide input voltage range from 16V to 160V DC, complying with the input battery voltage transient ranges of EN50155 (2017). The industry standard half brick package offers high efficiency levels up to 91%. The fully isolated (4242Vdc) DC-DC module accepts a wide input voltage range from 16V to 160V DC, while maintaining a fully regulated single output. The output voltage features overvoltage, overcurrent, short circuit, and overtemperature protection. Other features include-adjustable undervoltage lockout protection, adjustable current limit threshold, positive or negative logic enable and a hold up pin to allow connection of an external capacitor.
