DESIGN CONSIDERATIONS

1) Recommended circuit

All the URA_ZP-6WR2 & URB_ZP-6WR2 Series have been tested according to the following recommended testing circuit before leaving factory

(see Figure 5).

If you want to further decrease the output ripple, you can increase a capacitance properly or choose capacitors with low ESR, but the greatest

capacitance of its filter capacitor must less than the Max. Capacitive Load.

Note:

1.Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically, If the product operate under min. load, it may not be

guaranteed to meet all specification listed. Operation under minimum load will not damage the converter.

2.Recommended Dual output models unbalanced load:≤

±5%, If the product operate >±5%, it may not be guaranteed to meet all specification

Listed, please contact our technical person for more detail.

3. Max. Capacitive Load is tested at nominal input voltage and full load.

4. All specifications measured at Ta=25

°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

5. In this datasheet, all the test methods of indications are based on our corporate standards.

6. All characteristics are for listed model, non-standard models may perform differently, please contact our technical person for more detail.

7. Contact us for your specific requirement.

8. Specifications of this product are subject to changes without prior notice.
