1. Maximum power must not exceed 180 W with convection cooling or 320 W for forced air.

2. With external 22 CFM fan.

3. 1% 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.
