1. How long should it take for Hi-pot test of LEB150F-0524?
Answer : Our test voltage/time is 1.1 times of specs/2 seconds. This is allowed by Safety Standard.
We do Hi-pot test for all products. |
2. What is the receiving inspection procedure of isolation test for DPF1000?
Answer : The test result is changed by earth capacitor. (= Y capacitor)
If Y capacitor is bigger than our test circuit, this model may not pass.
Because leakage current is increased.
And line pattern and FG pattern should be separated. (distance: 4mm or more)
Please check capacitance of Y capacitor and PCB layout. |
3. Can CDS4004828 meet EMC class B with external circuit?
Answer : Please check the attached pdf file. |

4. The isolation voltage of PBA150F-15-N between input and output mentioned in catalog is AC3000V. If we need AC4000V isolation, are there any other suggestions?
Answer : Isolation voltage of PBA50F-15-N is shown 3,000V on our catalogue.
However, when we tested isolation by 1 sample, the power supply was able to endure 5,000V approximately.
If the guaranteed isolation voltage of 4,000V is needed, we have to evaluate some subject.
For example, if internal component does not meet to this voltage, we will not be able to guarantee it.
Another method we suggested is to add the input isolation transformer. |
5. For SUCS102405B/ZUW252412/PBA50F-9, how long is the isolation voltage DC500V being test?
Answer : 1 minute |
6. Are there any inrush current level 4 standard of LEB100F-0524?
Answer : I think it is surge voltage not inrush current.
Since inrush current level is not decided by IEC directive.
If it is surge voltage, the power supply meets the level 4 of IEC61000-4-5(surge immunity). |
7. Can PBA30 series pass the 4KV isolation test between Input and Output?
Answer : We tested one sample for 4KV between input and output and it passed the test. |
