Notes

1. guaranteed by design, not tested.

2. Load and line transition time > 10 µs

3. Unit will shut down above approximately 425V but will be

undamaged and will restart when voltage drops into normal

range.

4. Recovery time is measured from application of the transient to

point the point at which Vout is within 1% of final value.
