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. The purpose for more stable at the output terminal, the output voltage of 3.3VDC requires to add an 330uf E-Cap.The output voltage of 5VDC, 12VDC and 15VDC require a 100uF E-Cap to stabilize the output terminal. The output voltage of 24VDC, 48VDC and 54VDC are not necessary required for E-Cap.

5. Do not exceed maximum power specifications when adjusting the output voltage.

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

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