NOTES

1. Transient recovery time is measured to within 1% error band for a step change in output load from 50% to 75%.

2. This power module is not internally fused. We recommend protecting the converter by a slow blow fuse in the input supply line.

3. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor 330µF/100v.

4. This product is listed to applicable standards and requirements by UL.

Due to advances in technology, specifications subject to change without notice.
