Design Feature Considerations
Maximum Capacitive Load
MSAU400 series limitation maximum connected capacitance output. power module operated current limiting mode during start-up, affecting ramp-up startup time. maximum capacitance found data sheet.
Thermal Considerations
Many conditions affect thermal performance power module, such orientation, airflow over module board spacing. avoid exceeding maximum temperature rating components inside power module, case temperature must kept below 90°C. derating curves determined from measurements obtained experimental apparatus.
Input Source Impedance
power module should connected ac-impedance input source. Highly inductive source impedances affect stability power module. applications where power supplied over long lines output loading high, necessary capacitor input ensure startup. REV:0 2005/04
