Ripple and noise are measured at full load, 20 MHz BW with 10F tantalum capacitor and 1F 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 470F for 24 Vdc input models and 47F for 48 Vdc input models is recommended to reduce input ripple voltage.
