The SV28-3.3 series is a family of 28V input, 3.3V output, half brick modules compatible with the industry standard footprint. These modules may be used as form, fit, and function replacements for industry standard, 3.3V half brick modules. These SuperVerter modules use metal baseplates, planar transformers, and surface mount construction to produce up to 132W of low noise, 3.3V output power.
