1. What is the minimum input voltage of CBS1004812,CBS1004805 and CBS2004824-XCMNA that it can work properly ?
Answer : The minimum input voltage COSEL guaranteed is DC36V. However, these units have capability to start-up at 31V approximately, and if input voltage reached 33V, the rated output voltage will be generated.
However, in the input voltage range between 33V and 36V, the input current is increased due to low input voltage. Therefore, the load should be derated. |
2. The input voltage range of DBS400B modified version is 250VDC-400VDC. If the input voltage is less than 250VDC, is the power module in input undervoltage lockout or not working?
Answer : DBS series are using lockout circuit.The start-up voltage of DBS400B28-XTHIA is more than DC180V.
By the way, the start-up input voltage and rated input voltage range is different things.
If DBS400B28-XTHIA and DBS400B12-XMLM are used under DC250Vin, we can not guarantee the specification. |
3. Can PBA1000 series work properly with input voltage AC280V?
Answer : We are not able to guarantee AC280V input.
Because the voltage exceeds the maximum rated voltage of components.
PBA1000F could operate at AC280V. However, we don't recommend this. |
4. Can LCA30S-12 work at 100% load with input voltage range 85V-90Vac?
Answer : If the input voltage is AC80V, the load must be decreased to about 94% max. If input voltage range is AC85~90V, it can be worked normally at 100% load. |
5. What is the input surge withstand (input voltage and time) ability of CDS6002428?
Answer : 50V, <100ms |
6. Can PBA300F-24/PBA300F-48 operate with input voltage range from DC70 to DC166? Because we don't want to use power module.
Answer : U option of PBA300 series can operate at low input voltage by derating of output power.
However this model needs the input voltage of more than DC90V for start-up.
And this models can operate at DC70V after being start-up. |
7. Requirement: DBS series Po=550W; Vo=24V or 28V; Vi=DC200-400V
Can you recommend the suitable power module? Please provide the model no.
Answer : The power module of 550W output must be used in Vi=DC250-400V.
Because when input voltage is DC200V, input current will be too big.
So if customer uses the power module in Vi=250-400V, we will be able to recommend the below models.
28V output: DBS400B28-XLPG 28V,19.7A rated
24V output: DBS400B24-XNHMB 24V, 23A rated |
8. Does CBS2002415 has input overvoltage protection ?
Answer : No, CBS series doesn't have overvoltage protection for input. |
9. If CBS2002415 haven't input overvoltage protection function, how to prevent input overvoltage ?
Answer : Rated input voltage range is maximum value for this module.Please use a constant voltage power supply to input power. |
10. If input voltage is abnormal such as DC60V or DC80V, will CBS2002415 burn or explode ?
Answer : Smoke and fire will not be caused. External fuse will be blown by breaking internal circuit. |
11. Please provide the external circuit diagram of CBS1002415 with below requirements. Input overvoltage protection function: the power module will be shut down when input voltage from DC37V to DC60V. When the input voltage becomes normal,it can restart to work automatically. Moreover, the power module must endure input voltage DC500V at 10ms.
