Ripple and noise are measured at full load, 20 MHz BW with 10µF tantalum capacitor and 1µF ceramic capacitor across output. The 48 Vdc output models require a 10uF aluminum capacitor and 1uF ceramic capacitor across the output. 2. An external input capacitor of 470μF for 24 Vdc input models and 47μF for 48 Vdc input models is recommended to reduce input ripple voltage.
