QAxxl Series MORNSUN* DC/DC Converter for IGBT driver FEATURES • High efficiency up to 81% • Ultra Compact SIP package • Isolation voltage: 3K VAC • Max. Capacitive Load:1000uF • Ultra low isolation capacitance • Operating temperature range: -40°C to +105°C • No-load operation allowed QAxxl series are DC-DC converters for IGBT drivers. Their ultra low Isolation capacitance can Improve the capability of anti-interference. The bullt-ln common-ground mode of the unique asymmetric voltage output mode reduces the driverloss ofIGBT 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) Patent Protection RoHS Selection Guide Input Specifications Output Specifications MORNSUN GUANGZHOU SCIENCE & TECHNOLOGY CO.,LTD.

THIRD ANGLE PROJECTION Front view Bottom view Unit :mm[inch] 1. Packing information please refer to Product Packing Information .Packing bag number: 58200013; 2. The lead wire connecting the power supply module and IGBT driver should be as short as possible during use; 3. The output filtering capacitor should be as close as possible to the power supply module and IGBT driver; 4. 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; 5. The average output power of...
