ABSOPULSE ELECTRONICS HVI 41R-F1 50W high input voltage railway quality dc-dc converter employs the latest silicon carbide (SiC) semiconductor technology to deliver high conversion efficiency, high power density and a smaller form factor than similar designs with the same output power. It measures 114 x 51 x 201mm. Unit operates from 750Vdc (525V to 975Vdc), the traction voltage required for mass transit vehicles including trams, metros and light rail, mining locomotives and trolleybuses. Unit also incorporates input surge withstand capacity of 1300Vdc, and delivers 24Vdc/2A regulated output.
