VI-ARM-H122 Description

Short technical summary and product information.

The Vicor VI-ARM-H122 is an Autoranging Rectifier Module (ARM) designed to provide autoranging line rectification and inrush-current limiting. This AC front-end module interfaces directly with worldwide AC mains and is compatible with Vicor's VI-200/VI-J00 series DC-DC converters, as well as Maxi, Mini, and Micro series DC-DC converters operating at 300V IN. This allows for the realization of autoranging, high-density, low-profile switching power supplies.

Key specifications include a power rating of 500 W to 750 W. The operating temperature range for this module is typically -20°C to +100°C, with some variants offering -40°C to +100°C. Various pin styles (Short, Long, ModuMate) and baseplate options (Slotted, Threaded, Through hole) are available to suit different mounting and integration needs.

The ARM module is part of Vicor's modular approach to power, offering flexible and scalable solutions. It is suitable for applications requiring efficient AC front-end processing before conversion to lower DC voltages.
