HVI 41R-F1 Railway DC-DC Converter
Featured Product from ABSOPULSE Electronics Ltd.
ABSOPULSE Electronics has released the HVI 41R-F1, a 50W addition to its line of high input voltage railway quality DC-DC converters. The 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 201 mm.
The HVI 41R-F1 converter operates from 750Vdc (525V to 975Vdc), the traction voltage required for mass transit vehicles including trams, metros and light rail, mining locomotives and trolleybuses. It also incorporates input surge withstand capacity of 1300Vdc. The unit delivers 24Vdc/2A regulated output. Custom input/output values are available on request.
