Global No.1 Innovator EGTRONICS

ACU28V3K

• Uni-Directional DC-DC converter that transforms the high voltage into a low voltage to supply 28V power to the electrical load of the eco-friendly vehicle.

• Developed for mass production for overseas market; output voltage can be adjusted for various applications
Operates 2-3 converters in parallel according to the electric capacity of load.

• This module can be integrated with other systems such as OBC (On-Board Charger or MCU (Motor Control Unit).
