P048F048T24AL V•I Chip Pre-Regulator Module is a very efficient non-isolated regulator capable of both boosting and bucking a wide range input voltage.
The Vel Chip Pre-Regulator Module (PRM) is a non-isolated regulator designed to provide a controlled Factorized Bus voltage for powering downstream Voltage Transformation Modules (VTMs). It features an Adaptive Loop feedback mechanism that allows precise control of isolated Point-of-Load voltages using a single wire, eliminating the need for traditional remote sensing or isolation devices in the feedback path. The module supports both bucking and boosting across a wide input voltage range.
| Input voltage range | 36 - 75 Vdc |
