Notes

1.Ripple & Noise dependent upon output voltage as specified per particular model.

2.Minimum load is NOT required for proper operation.

3. Load regulation is measured from 20% ti FL.

4. Line regulation is measured from 90VAC to 264VAC.

5. Preset accuracy measured at nominal load, 115VAC input.

6. O/P noise measured at directly at pins at max. load, with a 0.1uF/ceramic capacitor bypass, pk-pk @ 20MHz bandwidth.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
