CBPatent Protection RoHS
QA series are DC-DC converters for IGBT drivers. Their ultra low isolation capacitance can improve the capability of anti-interference. The
built-in common-ground mode of the unique asymmetric voltage output mode reduces the driver loss of IGBT driver. They feature
short-circuit protection and auto-recovery , and can be widely used in:
1. General inverter
2. AC servo drive system
3. Electric welding machine
4. Uninterruptible power supply (UPS)
