Notes:  
1. Maximum total combined power  
2. With external 16 CFM fan  
3. 10% minimum load is required to maintain the ripple and regulation.  
4. Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 μF ceramic capacitor and a 22 μF electrolytic capacitor in parallel.
