QA2401C-20 is DC-DC module power supplie designed for IGBT driver requiring two set of isolation power supply. The mode of mutual
connection after two independent outputs is adopted internally for better energy provision of SiC turn-on and turn-off. Output short circuit
protection and self-recovery capabilities are also provided. General application includes:
1.Universal converter
2.AC servo drive system
3.Electric welding machine
4.Uninterruptible power supply (UPS)
