1. Is the internal current balance circuit of DBS400B24-XNHM or DBS400B24 using Control IC UC3902?
Answer : These power supplies don't have UC3902. |
2. Can DPF1000 and DBS400B24 pass the vibration test in 5-500Hz (0.75G)?
Answer : We haven't tested DBS and DPF. However, CDS passed the same test.
So, we think that DBS and DPF will pass the test. |
3. SUS1R52405 / SUS1R50505 / SUW1R52412 /SUW1R52415 Can you tell me the calculation method of MTBF?
Answer : The MTBF is calculated by EIAJ RCR 9102 in our company.
EIAJ RCR 9102 means "Part count reliability on the DC stabilized power supplies".
In this report, the failure rate of each component are decided as fixed value at all condition.
Therefore, MTBF is same value at all condition.
The formula is the addition of all component's failure rate |
4. Can DBS100A13R8 be modified to output wattage in the range of 120W to 150W?
Answer : It is simply by adjusting DBS150A15 to output voltage13.8V, the module can generate 138W. (13.8V, 10A). |
5. Can the power module withstand 35G impact? (Time: 1000 times in half hour)
Answer : It is very hard condition.Power module may break by impact.Please avoid this condition. |
6. It the Vin- and Vo- terminal is short, is the isolation no use ?
Answer : Yes, it is not isolation power supply |
7. If PBA50F-9 output current is 1A, will it interfere the input terminal ?
Answer : No interfere. The input current decreases only |
