Notes:
1. Ripple and noise measured at full load, 20 MHz BW with 10μF tantalum capacitor and 1μF ceramic capacitor across output.The 48 Vdc output models require a 10μF
aluminum capacitor and 1μF ceramic capacitor across the output
2. An external input capacitor of 1000μF for 24 Vdc input models and 330μF for 48 Vdc input models is recommended to reduce input ripple voltage.
