Global No.1 Innovator EGTRONICS

ACU14V3K

Uni-Directional DC-DC converter that transforms the high voltage into a low voltage to supply 12V power to the electrical load of the eco-friendly vehicle.

This module can be integrated with other systems such as OBC (On-Board Charger) or MCU (Motor Control Unit).
Features
  • Galvanically isolated type
  • Maximum efficiency : 96% or higher
  • CAN 2.0 Interface (J1939 Standard)
  • EMC : ECE R10 Satisfied
  • ZVS (Zero Voltage Switching) topology ensures very low switching losses and excellent EMC behavior
