DC/DC Converter for IGBT Driver QA Series DC/DC Converter for IGBT driver Efficiency up to 80% Ultra Compact SIP package Good temperature characteristic Ultra low isolation capacitance Operating temperature range: -40℃-+105℃ No-load operation allowed CB Patent 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) Selection Guide Input Certification Input Voltage(VDC) Nominal(Range) Input Current(mA, Typ.) full load/no-load Efficiency Output Voltage Output Current (%,Min./Typ) @ Full Load (VDC)+Vo/-Vo (mA)+Io/-Io +15/-8.7 Input Specifications Item Operating Conditions Input Voltage Input Filter Filter capacitor Note: QA01* refers to all models begin with QA01.

DC/DC Converter for IGBT Driver QA Series Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing bag number: 58200013; The lead wire connecting the power supply module and IGBT driver should be as short as possible during use; The output filtering capacitor should be as close as possible to the power supply module and IGBT driver; The peak of the IGBT driver gate drive current is high, so low internal resistance electrolytic capacitor is recommended to be used for the power supply module output filter capacitor; The...
