MEC series AC-DC converters

Product Overview

The MEC series AC-DC converters are high-reliability DC converters primarily used for aviation/space electronic equipment. The modules are sealed with low expansion coefficient, high thermal conductivity potting compound, and can operate in a continuous temperature range of -55℃~85℃. They have good environmental adaptability, resistance to shock and vibration, salt spray resistance, and resistance to humidity and heat. They comply with the GJB151B electromagnetic compatibility emission and conduction interference standards. All internal components are domestically manufactured.
