Step down and boost DC DC Converter FAQ

 

Question： Regard as constant voltage and constant current DC-DC Converter

Answer:

A. Constant voltage DC-DC Converter

For example:

1. 24vdc-12vdc 10A, 12vdc output is fix, but the current output is automatic adaptive base on the load.

2. If you connect the load not work at 12vdc , the dc converter will be burn

B. Constant Current DC-DC Converter

For example:

1. 24vdc-12vdc 10A , 10A output is fix, but the voltage output is automatic adaptive base on the load.

2. If you connect the load not work at 10A , the dc converter will be burn

 

Question：Isolated & non-isolated DC-DC Converter

Answer:

l Isolated DC Converter is no any interference, it is suitable for sophisticated equipment and there is no any ripple

l Isolated DC Converter with ripple

l DC –DC Converter we design is non-isolated

 

Question：Step down & Boost & Automatic Step down and Boost DC-DC Converter

Answer:

l Step down DC-DC Converter-- Input voltage must be more than 2V/more of output voltage

l For example:24Vdc to 12Vdc 10A

l Boost DC-DC Converter-- Input voltage must be less than 2V/more of output voltage

l For example :5Vdc to 12Vdc 10A

l Automatic Step down and Boost DC-DC Converter--- output voltage between the input voltage range

l For example: 9-14Vdc to 12Vdc 10A

l When 9VDC Input, it can support output 12V; When 14Vdc input, it can support output 12Vdc also; input voltage between 9-14V constantly beating the same can be stabilized output 12V;

 

Question:  Can you customize USB dc dc converter?

Answer:

Yes.

 

Question:  Can you customize multi-output dc dc converter?

Questions: What is the difference between the PCB case type and the Aluminum case type?

Answer:

l Aluminum case type is waterproof

l The PCB case type is non- waterproof, but with Lightweight.

 

Question: Can you make the dc dc converter with adjustable output volatage?

Answer:

NO.  We can only make it stable output.

 

Question: Can you make the dc dc converter with adjustable output current?

Answer:

l NO.  

l We can only make adjustable output current mode.  

l For example one 0-10A model dc dc converter,  if you connect with right load, all things will goes well. No need to make stable output.
