Note:

1. Add a 0.1uF ceramic capacitor and a 10uF E.L. capacitor to output for ripple & noise measuring @20MHz BW.

2. Voltage accuracy is set at full load.

3. Line regulation is measured from 100Vac to 240V_acwith full load.

4. Load regulation is measured from 10% to 100% full load.

5. Typical efficiency at 230 V_acand full load at 25℃.

6. Forced air convection with 21.9CFM above 110V_ac.

7. With addition cooling conduction plate, 38.1 by 38.1 cm with min. 0.2 cm thick, as below.
