Ordering Information：
- Measured from high line to low line.
- Measured from full load to zero load.
- Output ripple and noise measured with min. capacitor 470uF and 1uF ceramic capacitor across output.
- An external input capacitor 330uF for all models are recommended to reduce input ripple voltage.
