The wire between the converter and IGBT driver must as short as possible. External filter capacitors should be connected as close as possible to the converter and the IGBT driver. The output average power of the IGBT driver should be less than the output power of DC-DC module. Maximum capacitive load is tested at nominal input voltage and full load. Note: 1. All specifications are measured at Ta=25°C, humidity <75%, nominal input voltage and rated output load unless otherwise specified. cui.com For more information, please visit the product page.
