For Those Who Need ControlThe Highest Power Density Bus Converter Module

High Voltage Bus Converter Module

Vicor’s VI Chip High Voltage BCM Bus Converter 6123 offers extremely- high power density in a compact, efficient package. With up to 1.75 kW at 50 V with 98% peak efficiency and power density of 2750 W/in3, the isolated, fixed-ratio power converters deliver 5X the power density of competing solutions.

Digital telemetry and control capabilities are available as an option for both 1.2 kW and 1.75 kW modules. This PMBus-compliant digital interface option gives system designers access to the internal controller, enabling digital communication with an array of VI Chip BCM Bus Converters via a single bus for control, configuration, monitoring and other telemetry functions. Standard BCM features include bidirectional operation, under- and over-voltage lockout, as well as over-current, short circuit, and over-temperature protection. The Vi Chip BCM Bus Converter 6123 enables efficient, high voltage DC distribution infrastructure in datacenter, telecom, and industrial applications.
