On-board-FAQs

Isolation or Non-isolation: How to Choose the Right Power Supply?

Most engineers still focus on meeting the input and output voltage and power load requirements when selecting power supplies, which is only the most fundamental requirement. With the continuous development of the industry, the needs of customers vary accordingly. Some only require the function realization and low price; some require to meet the high reliability and low fault tolerance rate, which is caused by the different directions in selection. In general, the selection mainly focuses on conventional parameters, important parameters, and some hidden parameters that are not usually noticed. Of course, reliability is the most concerned parameter at this stage.

Why does the mark of the products show 100VAC-240VAC while the datasheet shows 85VAC-264VAC?

This is mainly for safety certification purposes. When certification authority tests product performance, they will make the input voltage range on the mark fluctuate by +10% and -15%, so the common practice in the industry is to set the input voltage range of 100VAC-240VAC on the mark.

The AC/DC Converters produce instantaneous high current upon load access. Does this influence the module?

If the large instantaneous current of the AC/DC Converters upon load access does not exceed the over-current protection point of the module, it will not have any impact on the module. See the datasheet for the over-current protection point of the module. If the current exceeds the over-current protection point of the module, the module will trigger the protection and voltage dip occur, and then recover.

What is the possible reason for the surface temperature rise of the power module case?

The temperature rise of the power module case depends on the efficiency and loss of the module, and the surrounding environment temperature. Under the normal circumstance, the temperature for power module will remain stable within 30 to 60 minutes upon start-up. The temperature rise is continuously ascending in the earlier stage. If the power module is in a confined space without an effective heat consumption output, the environment temperature will keep rising due to the presence of the heating elements, which also causes the temperature rise of the module.

Why do the positive and negative voltages change when the load of AC/DC positive and negative dual output products is unbalanced?

AC/DC multi- output products generally apply single output feedback design. The output voltage without feedback will fluctuate when the output load is unbalanced. Most of our AC/DC positive and negative dual output products adopt negative output voltage feedback design, so a load imbalance will cause a change in positive output voltages.
