400V to 220V DC-DC Converter Step-Down - High-Voltage DC Conversion
DCC-400V-220V-50-400A
The Hannibal DCC-400V-220V-50-400A is an industrial DC-DC converter designed to convert one DC voltage level into another stable DC output for critical industrial, telecom and substation systems.
Overview
The Hannibal DCC-400V-220V-50-400A is an industrial DC-DC converter designed to convert one DC voltage level into another stable DC output for critical industrial, telecom and substation systems.
The DCC Series combines high-frequency IGBT conversion, compact cabinet design and electronic protection to support reliable voltage regulation in demanding DC power architectures.
